No start, but does run with Starting Fluid, spark.
Pull plugs, they are dry. No smell of gas.
pulled injectors,they are dry. rail full of gas, don't know the pressure though.
Turn the key and I can hear the fuel pump relay click and hear pump run.
Load test on in tank pump, pulls 3-4 amps at fuse
Load test on Main fuel pump, starts at about 9amps, then drop to about 4after relay kicks off.
Did the plug in diagnostic check and:
1) I hear the injectors clicking
2) Fuel Pump does not run
3) Electric fan does not run.
4) IAC and charcoal canister work.
If I Jump the Radio Suppression Relay, do not hear the fuel pump run, and voltage here, with key in off position, between RED and GREEN/RED STRIPE wire, starts out at 12. then starts dropping off slowly. Did this with two different voltmeters. With key in Position II, voltage is 0.
With key at II, voltage between each side in injector plug reads 13+ volts when grounded to chassis ground.
If I jump the Fan relay, it works.
Replaced FPR with one from pick-n-pull. Didn't make any difference.
Changed ecu to one from pick-n-pull. One of the relays, pretty sure it was the fuel pump relay, continuously buzzed?
Any electrical gurus out there? I've been working on this as time allows. As I mentioned in a previous post on this no start. The car had been sitting, and I would start from time to time.
I could pull injectors and have them cleaned, but I would think that they all wouldn't get blocked up at once?
