kind of tested this out last night. I had a friend hold the test light while I tried starting the car. The car didn't start. The test light would also shut off while I crank, It would slowly dim out. But due to the fact I work on it in the street and live on a corner, It's kind of noisy and the pump isn't that loud. So Someone has to be by the tank to hear it. So we really didn't check to see if the pump turns on. But no, the car didn't start.

My Helms shows there is a fuse link(k) in the red wire coming off the fuel pump relay,have you checked that?

Try jumping 12v directly to the pink/blk wire in the relay plug from either the orange wire or the battery - that should turn on the pump so you can see if there are any other EEC-related problems preventing startup of the motor. But, even if the motor starts, you still need to address the problem of "what's preventing the EEC from grounding the relay"? (Jeff probably knows) [Image: smile.gif]

When you turn on the ign sw power is applied to the EEC relay which sends power to the fuel pump relay. The computer then cycles the fuel pump relay. If the EEC relay is energizing there should be power at pins 37 and 57 of the computer. Check for power at these pins as well as pin 1, also pins 40 and 60 should be grounded. If all these points are good you likely have a bad computer.

Jon, Correct me if I'm wrong but the red wire is the one coming from the inertia switch. Which is getting power at the Fuel pump relay and the inertia switch. So that would leave me to belive that the fusible link is fine. But of course there is always a possibility so I will check it A.S.A.P. Any Idea where it is located in the car?

Jon - Is the fuse link in the red wire (ign sw feed) or the orange wire (f/p power source)? He said he's got power at the red when the ign sw is on and that the relay clicks when he grounds the tan wire with his test light - so I suspect that if it's in the red wire, the f/link is OK.

Twin - Most f/links are located in the wires coming off the starter solenoid.

TurboRay, Like I said in my main post. I jumped a wire coming off the inertia switch(RED) to the fuel pump(Pink) this way The pump should turn on with the 12V source only when the key is turned on. The pump does then turn on, but the car still lacks to start. Like I said before, I think the computer isn't telling the injector to go.

Just want to say, I checked all the F/links coming off the starter solenoid. None appeared to be melted or anything. Checked to make sure they are all getting power. Everything checked out there.

Do the injectors click when you crank the car. Cuz if they don't, it sounds like you aren't getting PIP signal to the EEC. But, you SAID you had spark (??!!). If you have spark and the injectors aren't clicking (assuming all the connections are good in the harness plugs, etc.) - you may have a junk EEC!

I do have spark, didn't check to see if I have clicks from the injectors yet. But on another note. I still have the merkur stilling in my driveway. I can pull the puter out of it and see if she starts. Will the merkur/LA3 pinouts be close enought for now just to see if that is my problem?
