Won’t start

Five days of ownership, so tonight would not start, good battery, turns over well I get a initial fire but that’s all. Not more than a second then nothing. Turns over but nothing. So I know the L Jetronic system from my Alfa and D Jetronic from the Jag, so what is in the 87? When I turn the key on I do not hear the fuel pump run for a few seconds like my other cars. Is there a cold start injector? It ran well here from Florida no starting issues at all. Even with a bad cold start injector can you start the engine.

87 five speed.

Are you sure that it's a fuel related problem?
As Rich says, replace those 3 relays first.
Remove the airbox and try spritzing the throttle body while cranking. If it fires when you spritz it, it is definitely fuel related.
Is your fuel pump functional? Remove the relay XX (top row and 4th from the right) and use a jumper wire from terminal 30 to terminal 87. This will power your fuel pump constantly whether the key is on or off, so don't leave it jumpered when you are not working on it. Is your fuel pump working with the jumper? If not, check the fuse( fuse #42) If it is still not working, the fuel pump is probably FUBAR and needs to be replaced. REMOVE THE FUEL PUMP JUMPER WIRE WHEN YOU ARE NOT TESTING YOUR FUEL PUMP!!!!
Keep us posted after you test.

Have ordered new relays with the resistor, got 6 to have spares, and a set of CARAX fuses that glow when blown, got the big set and will change out every fuse. Jumped the pump relay and can hear the pump running, so it looks like Saturday will be trouble shooting the system.
Will get the relay puller, always fun buying new tools and Lisle makes some great tools.

So my A&P came by today he had a timing gun we put the pickup on a plug wire and when I cranked the light flashed, then we pulled the air cleaner and sprayed engine starter into the throttle bode and it ran. So it looks like a fuel issue since I have spark. I guess next would be pull the ECU and air flow body and have them rebuilt.
The fuel pump runs with the relay jumped.

Dan, was this car sitting for a while and not being driven?

If so, your injectors may be clogged up. You can unclog them with various chemicals (my fav is Berryman's B-12). I made a jig to apply 9 volts to the uninstalled injector to which I attach a vacuum source to the top of the injector. I dip the nozzle end into the Berryman's, apply the vacuum, and alternate the 9v power between on and off. When the vacuum begins sucking the Berryman's through the injector, I move to the next injector.

There are also several commercial injector cleaners to which you can send your injectors for cleaning. It's pricey but cheaper than replacing injectors.

You can also use a noid light to test the power to your injectors prior to cleaning. If your injectors are clogged, however, even if your noid light says the injector is working, what is actually telling you is that the injector solenoid is working, but no fuel will be injected.

Well the long time owner had it 10 years in Michigan, he passed away last summer and his son drove it to Florida in September. Up for sale Toby got it six months ago and drove it to the Keys, I have driven it to Georgia 850 miles last Saturday. So clogged injectors are low on the list, my guess is still fuel. I do not believe this car was ever basket case because everything is very clean.

Ok great!
If you already replaced your fuel injection relay, and you still have the no-start, you could have a bad fuel injection ground or you need to have the LH rebuilt.

DHS,
I see you are in Georgia. There are several folks there that have a LH based fueled 928 that could test your LH in their car prior to having it rebuilt.
OR
You can send it to me and I will put it in one of mine to test. If it tests bad, I can contact you and find out your wishes and send it for you wherever you want to have it repaired.

I do believe that both Louie Ott and Rich Andrade will test your LH for free and I would not hesitate to send it to either one of those guys. Do not try to send it to a local rebuilder. You will not be happy with the result.

I sent the unit and MAF to Rich, just got them back, spent the last week cleaning ground points, have the new relays in and am pulling and cleaning each fuse. will probably be Saturday when I have her put back together, and will see what happens.
Will update then.
Dan

Sounds like a great plan! Good Luck

Update, Rich rebuilt ECU and MAF, put them in and pulled every relay and fuse and shot contact cleaner in each slot, one at a time.  Car ran fine for three weeks.  So started to work on the AC system, hot wire clutch and it worked, was able to charge the system.  Then kept trouble shooting the system, Kevin in Atlanta gave me the checks for connections compressor to control. My #9 pin wire from low pressure switch(LPS) is bad (broken in harness?) but I have power to the LPS so I put a relay under the starter post to get high power to the clutch. This now checks good but after this work the car would not start!  Will run on starter fluid so pulled the ECU and Rich just checked it and tested it in his 87 and it’s good.  Jumped fuel pump relay can hear the pump running, so while trying to check the AC wiring I must have bumped some thing to cause this.  All grounds have been cleaned and tightened.  Suggestions?  Will get ECU back in a few days.
Dan . AC clutch relay.

Did your 14 pin connector come undone at any point?

No it is zip tied to its post. I did open it when I needed to move it to get my new relay in and check the wires at the #9 pin. I cleaned out the corrosion (minimal) and sprayed it with contact cleaner put it back in the clip and went ahead and added a zip tie to it. The car still would not start so I pulled the ECU for Rich to test.

Just checking in case any wires in the 14 pin connector had gotten inadvertently moved. 

After you deoxited the fuse panel, did you put any additional relays where there hadn’t been before?

The 14 pin connector was intact and I removed each relay one at a time and used the contact cleaner also each fuse one at a time.  The only relay I have added is the one for the compressor clutch. 

So, if you jumper the relay for your fuel pump, the engine starts and runs?
It sounds as if your "new" relay coincidentally got old and quit working far ahead of it's projected failure schedule.
What happens if you replace the fuel pump relay with a different relay?

No even with the jumper and I can hear the fuel pump running it will not start.  The only relay I have added is for the AC clutch power.  Rich checked the ECU and even put it in his car for a test drive, it checks good.  Just got it back today will put it in in the mourning and try testing something.  I guess I will test all three new relays just to be sure, then recheck for spark with starting fluid.  Kevin in Atlanta has sent me some materiel to look at and so has Rich.  I would love to get the car back on the road, even considering trying to make the South Coast meeting.  It would be a long haul but I would like to meet some of the other owners.

  So I have ECU in and checked the fuel pump relay in the horn.  Also used this special relay jumper (see photo) and can hear the pump run still no start. All the grounds are good/cleaned so looked over the engine all connections look good. 
Next?

well hooked up a pressure gauge and the fuel pump on it went to 56 psi so i know it flows fuel.

Hi,
In this thread you suggest replacing the fuel pump, EZF and LH relays.  Do you know the part numbers for these relays and what position are they found on the main ciRcuit board?  I have a 84 if that matters.
thank you,
tim

DHS, What you do actually know is that the fuel rail has fuel and pressure, but apparently no fuel is passing through your injectors. Your 928 is an 84 US., correct?
Either place a jumper in lieu of or replace the Fuel injection relay XVI (which is a specific relay: 928.615.119.00 ) located fourth from the right on the top row of relays.
If you jumper that relay, I believe you will need a 3 prong relay: terminals 30 to 87 and 87a.
If you have a NOID light, you can test any relay to see if it is receiving a signal. Chances are that they are not receiving a signal.
Good Luck.

Tim,
Start relay is XIV (fifth from the right on the top row) - standard 53 relay
Fuel injection relay XVI (fourth from the right on the top row) 928-615-119-00 -  (specific relay only)
Fuel pump relay XVII (bottom row next to the double wide relay at the far right) 928-615-113-01 (specific relay only)

These are for an 84 US only. Euros (ROW) are slightly different
