So I have a 98 Dakota Sport everything seems to be working but it won't start. I replaced the cap and rotor and crankshaft position sensor still nothing. I had a CEL and scanned it and some codes for evap stuff came up but said it was most likely the canister purge valve so I bought one put it in still not starting ended up returning it. I have no idea what to try checking next. By the way i did spark plugs, wires, and fuel pump about 2 months ago. The ignition coil is sparking checked it with a multimeter and the fuel pump turns on.

 

Need to check fuel pressure, and if you are getting injector pulse.

 

How would I go about checking pressure? & when the fuel pump went out and it wasn't getting fuel I was able to barely start it with brake clean this time I tried and doesn't react to the brake clean at all.

 

If you are getting spark to the plugs, and it still won't run, then you either have too much, or not enough, fuel. If the plugs are dry...... then 'not enough' would be the problem. If you put in a cheap pump..... they are notorious for just not lasting very long.

Is yours throttle body injection? Or port injection? What engine ya got?

 

I'll post a picture I bought the precise 22 gal fuel pump it's one of the economy pumps on Rockauto. I have the 3.9 v6 and it's port injection.

 

Also what do you mean by the plugs being dry? Are you talking about the spark plugs?

 

Yep. Try and start the engine, then pull one of the easy-to-get-to plugs.

With port injection, there *should* be a pressure port on the fuel rail. (drivers side, toward the back.) Looks like a big tire valve stem. You can rent a fuel pressure gauge from your local parts store to test it. You can get a noid light to check for injector pulse as well.
