Ran fine. Parked for 3 days. Went out to start it and it turns over but no start. If I spray with starting fliud, there's a little bit of firing, like 1 cylinder almost trying, poorly, but it's really breif then it dies qiuckly, nothing like a normal short run on starting fliud.



Switched Relays around
Checked all fuses with meter to be sure.
I don't hear fuel pump prime. No fuel pressure at rail. No voltage to the pump with key on.
No codes.
Replaced Crank Sensor and cam sensor
5v to throttle body, 8v to camshaft sensor plugs
Jumped the duty side of the ASD relay and nothing happened
I have 12v at the relay socket for the asd and TCM.
unplugged battery to clear but no change

Any help greatly appreciatted.

If there is no fuel pump prime when you turn the key to ON, when crank and cam sensors are not involved, then either the fuel pump relay isn't closing or the fuel pump is dead. The latter is more likely if it's original.

Thank you Bob. Woldn't it as least fire with the starting fliud even if the pump was dead?

I jumped the pump at the conector under the rear seat with a battery charger and the pump ran fine. I disconected pump from the batt charger and the car started and ran for a few seconds with the little bit of pressure the pump built up from testing it. (did it twice)

There is no voltage at the fuel pump relay, so I can not jump it there.

I tried using another key in case it was the security.

Does a bad crank sensor shut off fuel and spark? I replaced it, but maybe I got a bad new one?

I have voltage at the source side on the fuel pump relay. Same with the ASD. I have voltage at the fuse for the fuel pump. I tried jumping fuel relay and no pump. Tried jumping fuse too, no pump. I'm assuming source means power supply and load side means to pump side.

I ran 12v from the battery charger from the plug under the rear seat with + hooked to green and - hooked to black and it made it all the way up to the relay #87 socket.

Gotta take a break with working on it Wednesday. I crushed my neck a couple weeks ago and all this crawling around the car has made it a bit worse.

Any ideas on the fix, please advise.

Many Thanks,

Soooo Today..

I can't help but mess with the car eventhough I shouldn't be. I tried running a new ground to test, no luck. Hooked up original wiring harness again.

-----> Then I jumped the fuel pump relay one more time AND the pump came on, the car started, I quickly shoved in the relay and it stays running and starts normal.

I don't get it, maybe it just needed some inspiration after replacing the cam/crank sensors...

Thanks to everyone !!!
