Have you checked all of the fuses ..... The ecm sol fuse ......fuel pump fuse and the c3i fuse. These are the main fuses for the engine
Ecm functions . Also Besure to check the orange wire at the battery for a good connection .

One more thing to check is the oil lite sensor wiring under the turbo as in a fail safe if the fuel pump relays goes bad it acts as the relay and turns on the fuel pump when the.motor makes oil pressure. I have seen those fail and blow the fuel pump fuse .

Ok, i just went and bought a new relay. Still no pump priming. I checked the 15 amp fuse in the fuse box. Its good. The pump turns on when i connect the 12v source to it but the car does not turn on. I checked the fuse in the orange wire that goes to the battery and its good. To go back to what happened before the car shut off. I was driving normal and went to change lanes and noticed the car hesitate. I continued a bit more and i gave it gas. It started to hesitate and just died.after that, no more start. Slogn, what is the ecm sol fuse and the c3i fuse? What else? This really is frustrating!

Ok, i just noticed that the connector for the oil pressure sensor had come off. I reconnected it but still no power at the fuel pump?

When i crank the car, i hear no pump on when i turn the key forward. I crank and it does not turn on. When i stop cranking it over, i hear the pump on for a second-two and shut off. This is driving me insane!

I am not getting spark at the spark plug. I did the screwdriver to metal test.

Pull a plug, then put it back in the wire and lay it on engine / ground then have engine cranked to see if the plug fires. This should help eliminate coils and or module problem. Heard stories of bad grounds at module driving guys crazy, I imagine process of elimination is in order. Good Luck, keep us posted

No spark when i pull it and test it on engine.

I think by trying each plug wire 1 at a time from each coil on that plug, I believe that should show each coils efficiency?
Old school way but if any coils send spark you can go in that direction. All 6 dead then next step ??? Module?? grounds??

It sounds like the you're eventually hitting the oil pressure bypass feed to the fuel pump. YOu have to build at least 4 PSI to power the pump through the oil pressure switch

Aminga, i cant the frekin car started,lol. Why wont the pump prime when i put the key forward? It seems a bunch of stuff broke at the same time or one thing caused a domino effect. I don't know. When you start the car in the morning, the car does not have 4psi of oil pressure when you put the key forward right? Is it that my relay or something else is still bad? If so far three plugs don't have spark, would it be safe to say that the ignition module is bad or is there another fuse or relay that i should check?

ok now here is the next thing to check is grab a test light and do some checking..... First with the key on check and make sure the injectors have power. If so then check and see if there is power on the coil pack plug. you will ed a 1/4 inch nut driver to take it loose. Starting from the left to right check and see if the pins 1 and 3 have power, These wires are pink with a black stripe. If you have power there the every nxt thing to check is going to be the crank sensor. They can fail and anytime with very little warning.


Another thing is have to tried another known good ecm? Does the check engine light come on when you turn the key on? IT's now time to go to the basics.


PM me your phone number and i can give ya a call and try to help a brother out!

Slogn, the injectors have power. Number one does not, number three does have power on the coil connector. Also, the engine light does not come on when i put the ignition forward. It used to.

Check or replace the CCCI fuse it's in the upper left hand side of the fuse box next to the top IGN 1 slot and to the right of it is the hole for the LPS connector not used on our cars unless you have aftermarket gauge lights hooked up there.

It should be a 10A yellow blade fuse.

It's right above the 15A FP/INJ fuse.

 

[SloGN]

If the check engine light is not on the fuse for the ecm is bad or the orange wire has a problem at the battery or the ecm itself is bad. Also if the c3i connector don't have power check the cci labeled fuse .

 

[dragrazor]

Where is the cci labeled fuse located?
Is it where salvage v6 says?

Yes.

I just checked all the fuses and they are all good. I think everything is leading to the ecm. How can i check to see if the ecm is good or bad? I read the vortexbuicks info on the ecm but its a bit confusing to me. I have the computer out where all i have to do is check the necessary wires
