Well I got some starting fluid, sprayed it in there and it started right up! I then took it out and drove for about an hour with out anything out of the ordinary. When I got home and shut her off I tried again to start her up...nothing just the car turning over and over like it has been doing for the past week.

The only thing I can think of is that your starter is sucking sooooo much voltage while it is cranking that nothing else is getting power while it is cranking, or something is sxcrewy with your pcm during the cranking mode where it wont open the injectors.

I'm at a complete loss with this already! I don't know what else to do.

Well the car still doesn't start after sitting for a few hours/days either! I can hear the fuel pump come on and off when I turn the key.

Also when the car was idling it would idle a little high. While I was looking at it I decided to unplug the MAF and MAP sensors. One at a time I unplugged them and they both caused the car's idle to drop. If they were bad wouldn't the idle stay the same? As for the opti I put in a new MSD opti back in August with new coil, plugs, and wires. So the connection is good because the harness is built into the MSD unit and the plug in is at the top of the intake manifold and it looks good. When I drove around it didn't miss or anything, I even did a few WOT runs from 1st to 3rd. I also have tried to smash on the gas when cranking it and it still doesn't start without the starting fluid.

How you making out robert???

Have you EVER before had a problem with the key cylinder on the column? Like turn the key to start and got nothing? Wiggle it a bit and then it goes?

^^^nothing ever like that.

I'm just gonna replace the opti again. It's only 5 months old so MSD will replace it for free. If anything it is worth a shot, plus the car will have a new opti for the nitrous going in!

If you checked and had spark at all the plugs then I fail to see how the opti is the problem.

I wonder if your injectors are stuck open or closed. Do you think its a possibility?

Also try plug noid light, watch if theres a injector pulse width.

joelster

It's not the opti. Your car started and ran fine with the starter fluid. Something is NOT telling the injectors to open on initial start-up.

Hey robert have you pulled a few spark plugs yet to see if fuel is getting to them??? Mabye the injectors aren't firing....

Plug noid light? I've pulled plugs lookin for spark. I'm driving it to work today so I'll see how it goes. How is the cam swap goin?

ya unplug the injector and plug in noid light, it should flash injector pulse width, that'll tell you if your injectors are working right. You'll have to do that with each injector one at a time. Have someone crank while you look at the light.

Well for anyone that was/is wondering...it was the TPS! It was reading over 4 volts so it wouldn't let the injectors spray fuel at startup. Replaced it with a new TPS and it fires right up everytime. Costed me $182 to finally get it fixed because I don't have an OBDI scanner and the mechanic charges out the *** for diagnostics! I need to invest in a OBDI scanner.
