Check the fuel pressure, to begin with. Even though the pump is working, it may be a weak pump. Low fuel pressure is often the cause of hard starting. If the pressure is good, you will have to start checking the ignition system for a fault.
Could be a long list of things including low fuel pressure, idle air control valve, a dirty throttle body, faulty throttle position sensor, faulty O2 sensor, and so on. Is the check engine light on ?
According to the parts book, the filter comes with the plastic lines attached, and should be in front of the gas tank. It makes a difference if the van is a long or short wheelbase model. Some models after 1996 had the filter in the tank.
stand outside your van,reach in the window and turn your key over,but not to the start position. you should hear a whirring sound from the rear of the van and it should last about 2-3 sec. this will be your fuel pump powering up. if you dont hear it,then you have a bad fuel pump. Dodge Caravans from 96-01 are VERY bad about eating fuel pumps. if the pump is fine,have someone try to start it while you look under hood and see if injectors are spraying fuel. if the pump is good,and you have no spray from the injector,then you have a clogged fuel filter which will need replaced.
Hi there, the problem could also lie with the fuel injectors / fuel pressure, burned valves, exhaust restriction, etc. Lots of things, for a more detailed list see http://www.obd-codes.com/p0300
Don't have access to actual pressure required at this moment but I will tell you that 12-20 psi is definitely not enough. Your probably looking at a minimum of 50-60, and as much as 90-100 depending on what engine. A replacement for a 3.3.L at autozone is rated at 90-100 psi. I'd spend the money on new pump & filter at same time.
if dont have sranner hook test light at injector groung side that would tell that crank sensor is working or the pump is weak hook up fuel pressure gauge and watch gauge
