I have a 96 Dodge Ram 1500. Cranks and runs fine but after it warms up it dies. After cooling off its as if nothing is wrong til it warms up again then dies and wont crank. Talked with one person that said...

I don't know what testing you have done? When it stalls if it cranks good but won't start, have a helper crank it while you visually check for spark at the spark plugs, if spark everywhere, use a gage and check proper fuel pressure. Also, check fuel injector pulse. If your missing all three, I usually check the cam and crank sensors. There could be other issues? Any applicable trouble codes?

I have a 1993 dodge d150 318 no spark or no power to fuel pump could it be the crank sensor?

A BAD CRANK SENSOR WOULD NOT CAUSE A LOSS OF POWER TO THE FUEL PUMP. ARE U SURE ABOUT THAT, THE FUEL PUMP ONLY RUNS FOR 1 SECOND WHEN THE KEY IS TURNED ON UNBLESS ENGINE IS STARTED. DO A FAULT CODE TEST ON THE COMPUTER, GO TO THE WEB LINK FOR INSTRUCTIONS AND A FAULT CODE LIST, VERY EASY TO DO.

1999 Dodge Ram 1500 318 engine no spark no signal to coil i changed cam positioner sensor and crank positioner sensor still no spark could it be a bad wire (ground)somewere

Check the ASD relay in the fuse box. Swap it with the starting relay. If the engine fails to roll over. Thats your problem. If not, check and see if your fuel injector connectors have voltage to them if not its a bad PCM. Hope this helps.

Check Engine light came on and car stalled

Crank Sensor usually have two function,1st the sensor sense the rotation of the flywheel and picks up by the sensor than the sensor send a sigle to your computer telling your computer to send sparks and fuel to to the engine. When sensor goes bad engine quits running, sometime check engine lights come on as computer is not sending no fuel or sparks. Some car has two sensor, one for the fuel and one for sparks. The sensor usually locate next to the flywheels near the main crank. Some are difficult to get to; others are easy. 4cyc on foreign are easy to get to compare to domestic. V6 front wheel drive I find it difficult and V8 rear wheel drive are better. If you plan to keep the car and fix it yourself, the best thing to do is invest and purchase Chilton Repair Manual if planning do it yourself, it will save you lots of money in the future. On 96' breeze should be a breeze to fix, from experience working on Dodge and Chrysler are fairly easy to work on.

We replaced the crank sensor and cam sensor on a new 5.2 engine in a 1998 Dodge Durango. We checked and rechecked the connections and still no spark.

check the wiring harness at the coil,sometimes that plug will get loose or dirty resulting in a no spark.
The only ign system parts are the crank sensor,cam sensor,dist,dist cap,rotor,spark plugs,wires,and coil,and the ecm which controls all of these,is there a check engine light on?
run a scan tool to check for stored codes or system events stored in the ecm.

Engine swap

I just put a 96 360 magnum in my 97 dodge 4x4 that had a 318 in it. Yes it does fit. I noticed that the flex plate on the 360 has balance weights on it and the 318 does not. Make sure the plate stays with the 360. The torque converter and exhaust manifolds bolted right up. The 96 360 engine had different connector plugs on the Map sensor, Crank Sensor and Tps. Get those off of your 318.
I did notice that with the 96 PCM for the 360 my fuel guage was off quite a bit. The 360 will run off of the 318 computer at least if your in a bind for Money.
