OK, that's more like it. the spec is 385-425 kPa (55-62 psi)

This is reaching a point that is going to require some serious testing using a lab scope and that's probably where your ability is going to end. This truck has no ignition module so these circuits are going to have to be mapped out and examined to look for the flaws in the wave pattern.

Can I just replace the ignition coil to check it?

That's one way to throw a bunch of money away.

the OE coils for this would cost you $640 or more for a set of 8 before you even buy the plugs and boots. You really want to spend that much money on a guess instead of getting it properly diagnosed for a fraction of that?

If you're that anxious to throw $400 away you can send it to me. If I were you I would spend $80 of that to have it diagnosed properly.

At $415 you aren't getting good parts, you're getting made in chi-wan-dia garbage with a sky high failure rate. Even at shop price I can't get near that using parts worth actually installing.

Re: My 2003 chevy silverado 2500 hit railroad tracks and died Sign In

It's all fixed . Turned out to be a MAF sensor. But now I have a squeal coming from by the firewall and it happens when I start the truck and push on the gas, it is nothing on the belt a machanic looked at it. Supposedly it's a vaccum leak... Any help I can't find it ..

If you already know it to be a vacuum leak, then you've already diagnosed it and all you have to do now is pinpoint it. I can't do that for you. If you can't find it you may have to get it smoke tested.
