87 Shelby Lancer Wont Start

[Lancerguy87]

I have an 87 Shelby Lancer and its been sitting since it died about 4 months ago I just haven't had the time to work on it till now and I have no idea whats wrong with it

I pulled the codes and got a 12 (battery disconnected),54 (no fuel cam sync),55 ???

I replaced the HEP and still nothing

The car is bone stock and just died one day on my way home from work then once I towed it the 2 blocks back to the house it started and ran for about 5 min then died and wouldn't restart

Since I'm sure most of you guys know a lot more about these cars then me
what else should I be looking at ?


I just to get this thing back on the road

Thanks
Aaron

fuel pump??? do you hear it when you turn the key half way,55 is end of codes

fuel rail schraeder valve a quick way to verify you got fuel P at the rail..

remove knurled cap, push pintle inside valve, squirt fuel in yur eye

hey - got spark ? check the basics... then

clear compy, recheck codes.. minimopar.net

I have good fuel pressure but no spark

[detobias]

theres some good electrical troubleshooting tech notes at

MiniMopar Resources

including (pretty sure) 'no start, no spark'

hmm try here

I hate guessing, proper diagnostics will lead you to the problem.
Code 54 which is the fuel sync signal from the HEP will create a no start.
The controller needs to know where #1 cylinder is to sync the injectors.
You say no spark, are the plugs fuel fouled? If yes remove and clean/replace, be sure the oil is not fuel diluted, change if necassary, fuel diluted oil will wash down the cylinder walls creating internal engine problems while cranking/running.
Be sure the battery is fully charged before proceeding.
Clear the codes, be sure they cleared and crank the engine for 10 seconds,(unplug the fuel pump so the engine does not get flooded again) did the code
54 return? If so that is where we are heading with diagnostics,POST BACK.
Also, code 55 is "end of message" meaning the controller is done communicating.
When you installed the HEP be sure you did not bend the wiring down the side of the distributor as the factory had it or internal damage to he harness will occur, be sure the connectors are tight and secure and free of corrosion.
If the code 54 DID NOT return proceed with the following diagnostics.
Reconnect the fuel pump, locate the underhood diagnostic connector(in the harness near the controller).
With the key on/engine off ground the DB/YL wire in the diag conn., this will actuate the ASD relay. The fuel pump should run and there should be power (batt voltage) at the
+ coil, DG/BK wire at the injector harness and at the HO2S (if equipped)
If all is present the ASD circuit is fine, proceed.... If 1 or more is missing POST BACK.
Remove your ground from the diag conn., unplug the fuel pump and while cranking the engine for 10 seconds check for power at the + coil, is power present while cranking?
If no the problem is in the HEP circuit, POST BACK.
The controller will not actuate the ASD until it sees a crank signal from the HEP.
If power was present during cranking POST BACK, the problem is related to the ignition control circuit, coil or secondary ignition, be sure the distributor is turning.
To verify no spark(with fuel pump disconnected) remove the coil wire from the dist cap and hold 1/4" from a good ground(more than 1/4" can result in damage to the controller) and crank the engine for 10 seconds, spark should be strong and consistant, count 1-2 sparks as no spark.

Well it still doesn't start but I've got spark and the injectors are firing ...my spark isn't a bright white/blue like it should be its a dull orange

I've got no codes now,my main problem was a wire with a bad splice (where the 2 orange wires from the HEP come together )

I've got power to the coil + as well as the injectors and the pump

I also replaced the distributor because the HEP window/vanes were loose I will re-time it on thursday and see what happens

Thanks for the help

this sounds like an odd think, but it has happened twice on my 87 Lancer.
the distributer got itself turned around by 180 degrees. Don't know how.
Did the timing gear jump? Or did the distributer just pop around by 180 I will never know.

So check to see if the rotor is pointed at the 1 spark plug post at the right time.
