SOURCE: 94 dodge grand caravan no fuel in fuel rail
Dear Ron, you have replaced fuel pump and fuel filter. You have checked the fuel pump relay. Still no fuel in rail. Try bypassing fuel relay with jumper from batt to fuel pump. If o/k then check computer for ground to relay. This system uses a relay that is operated by the computer that supplies a ground for the relay to operate. The wire color is green,16 gage. If the ground is not available then "no fuel" Check this with a test light. Key on and crank apply test light to ground wire and other end of light to ground. You should hear relay click and get fuel. If this checks out you will need to replace computer or get creative with rewiring the relay so it works without computer input. Good luck Moe

you need to put an oil pressure gauge on it and see what happens.what you will find is that the sender unit is no good.

The injectors are mainly controlled by the good output of an auto shut-down relay which is directly affected by the fuel pump relay straight from the PCM.The easiest way to check the fuel pump relay is turn on the key,wait a minute,and see if the fuel guage comes up to proper level,helps if you know fairly close how much gas you do have.A couple other things which could cause intermittent cranking are the ignition switch may be going bad,or a bad connection in the ignition wire harness but the ignition itself is way more common.Also a near dead battery.The lights will sometimes appear somewhat bright but to start requires lots and lots of power.A good battery should read near 13V.A bad one will read around 11.8,11.9V and could cause intermittent crank.A crank position sensor could cause it,but for the most part,if a sensor is bad the system either works or it does not.That's about all except do you have intermittent start or no start whatsoever,even jumpers?If this doesn't work or you need more help,just comment here and I will get an autolink to your post and reply ASAP.Good luck! Greg

Check the fuel pump fuse and relay, if it's OK, you have a bad fuel pump. About the no spark, could be many things
Ignition coil, distributor (if so equipment) , main shaft position sensor, computer problem
Good Luck
