      No. I rec’d a couple of suggestions from Scanner Danner that I will be trying tomorrow. Basically, he has me testing for 5v reference from key components like the TPS. I have got the 5v reference at the TPS so he says at the least the ECU is working to that component. I need to try a few more tests to see if I can narrow it down any further. The igniter is receiving power so I’ll be testing if power can be sent to the coils/spark plugs. If it can then I might be back to testing the fuel pump further or it may be a limited frying of the ECU. Any suggestions you may have I’m open for any help. Thanks.

        Okay, so I have tried to determine if the fuel pump is working but it doesn’t do anything when I turn the key to on. If I turn the key all the way to start the engine cranks and I can feel a vibration at the fuel line coming out of the fuel pump making me think the pump is working. I was going to pick up one of those inline spark testers to see if I am getting spark. The fuel gauge seemed low so I added about 2 gallons of fresh gas to the tank. Still will not start. I have checked every fuse under the hood and on the instrument block under the dash by the drivers leg. Every fuse is good. I also checked the relays both for continuity and by using a 9v battery to see if I could get them to click. They all tested good. Are there any fuses by the ECU on the passengers side of the car that I should check. I couldn’t find any. If I get one of those spark checkers and I’m not getting any spark what should I do to follow up on that situation. I also shot some car starter spray into the intake but again it only cranked did not give any sign of starting making me think it is a no spark or some other type of electrical problem. I will also try to get a better test on the fuel pump to confirm if it is working or not. I guess I should first check to make sure I’m getting power to the fuel pump. Does anyone know for sure that the pump comes on when the key is turned to “On” or could it possibly only work if the key is turned all the way to “Start”.
