Hi there.

The first thing we need to know whenever an engine won't start, is find out which of the basic 4 elements is missing; engine compression, fuel pressure at the rail, injector pulse and spark at the plugs. One way to shorten diagnostic time is by trying to start the engine on starting fluid - if it does start, we'll know compression and spark are good.

I don't know your level of expertise or what kind of tools you have, but if need be, you could borrow a fuel pressure tester from any major auto parts store. In addition, Noid lights to check for injector pulse as well as spark testers are sold there for less than $20 each.

Once we determine what's preventing the engine from starting, we can move on and look at any emission controls issues the vehicle may have.

Please let me know if you'd like to proceed as I've indicated. Otherwise, I'll opt out and let other experts try to help.

Not a problem. I'll opt out in case another expert wants to chime in. Please don't reply until the other expert responds or the site will cycle this back to me.
