I have a 1998 dodge caravan. I just replaced the cap, rotor, plugs, wires and new fuel filter assy. The car was running real good for a day and then it weas driving along and it lost power and quit. The engine would crank over but would not start. There was a strong odor of fuel which could be smelt inside and outside the car.

I still need to make sure the coil did not quit working but if that is not the problem.I think it could be a fuel problem like the fuel pump not working properly or the fuel regulator. How do I check to see if the fuel pump regulator is working properly and could this be the problem?

Do you hear the fuel pump come On? If so check the fuel pressure then report back or you can do below to determine if its a fuel or spark problem

Get a carb cleaner and spray into the carb or the throttle body on an EFI. Did it start and die? If not disconnect a sparkplug wire or 2 and ground it to the engine -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs, distributor pick-up coil, ignition control module, cam and crank sensors- Note: If it doesn't apply disregard it

If both fuel and spark is present-check the valve and ignition timing, this will lead you to problems with compression and valves opening and closing at the wrong time/broken or jumped timing belt/chain

I recently talked with you guys about my 1998 dodge caravan. The vehicle is running just fine when it runs but the problem is now this.

When the car runs for a while the fuel pressure blows the fuel supply line connection off at the point where it goes to my fuel rails. I was wondering a few things and that is this. Is the fuel roll over valves bad in tank causing high pressure, is my charcoal cannister plugged or my purge valve not working properly.

I replaced new fuel filter anyway because it needed to be done and I made sure that it was connected right. I also have been reading about some charcoal cannisters that have cleanable filters? I also am wondering if I have a leak detection pump if so is it bad.
I'm trying to get my mother in laws car fixed and it just so happened that the OBD-2 plug for some reason has no power so I am unable to use my scanner, Thank You for your time

Disconnect the fuel pressure hose and feel for vacuum-if none find out why-because the regulator is not maintaining the fuel pressure and also look for a clogged return line-
