The egr is brand new. How do I check the module and the coil? I have a multi meter.
Thankyou so much for your help.

The egr maybe brand new but is it hooked up right and does the solenoid work?
To check the coil and icm you need to check the resistance,It is fairly easy but you need a good manual so you know which terminals to check.

Take a look at your spark plugs. They can be a good indicator of what's going on in the cylinders. Your oil's not milky is it?

Just remember you need three things for a motor to run: Fuel, spark and air. To me, it sounds more like a spark issue. I would start with a tune up (which if one hasn't been done in a while, it should be anyway) and start there. Check the distributor, plugs, wires, check for arching, etc. Good luck and keep us posted.

check the timing. I had an 88 ranger throw the timing belt I replaced it myself, it idled beautiful reved up like crap. advanced the distributor and adjusted the timing belt again and ran great after. just my .02

Ok this is what I am down to, If I take the return line off the regulater with the motor running I get no fuel coming out what so ever.

So I think it is the fuel pump.

Ok think I figured it out, had my wife push on brakes while I rev under hood with intake boot off. I spray carb cleaner in and it runs awesome and wants to go.

So I almost positive it is fuel pump.

Get a fuel pressure guage and check it,also check everything from pump to fuel regulatoe before you replace everything,like I said before mine was just the hose from the pump that came loose.

What about IAC,or map sensor,on mine the distributor was bad also.

Well I fixed it it was the rubber line in the tank, I wasnt off but it was loose.
She runs good now except the tranny wont shift till 4500 rpm no matter what I do. The night I brought it home it shifted fine.

A few other people have had this issue with the resolution being a new throttle position sensor...I can't recall if that is something you've replaced or not. (as I'm using the 'quick reply' feature.) Good luck and let us know what you find!

here is a link to help with sensors i have used it alot there is a lot of other good stuff here to http://www.lunghd.com/Tech_Articles/...iagnostics.htm

Im thinking tps, I was getting 4.0 volts out now I am only getting 1.3 volts.

Change the tps if it is not 0-4.5 consistently,very common problem for tps to cause this problem.

Tranny is fixed I washed the motor and blew a fuse replaced the fuse and it drives and shifts great.

Thanks for all the help everyone, I am happy with the jeep now, I was about to run it off a cliff, but all is well now.
