I have a 1994 Plymouth grand voyager it has the 3.3 it cranks but will not start it's not getting no fire to coil.crankshaft, camshaft,ASD,fuelpump


No fire to the coil? Does that vehicle even HAVE a coil, or is it a coil PACK? Just to make sure the Automatic Shutdown Relay is not at fault, disconnect the battery for 10-15 minutes, then reconnect it and try it again ... but LISTEN carefully for a "groan" of about 1-2 seconds when you turn the key ON but not far enough to crank the engine. That will tell you if the fuel pump works. If there is no sound, with the battery connected and with the key in the ON position, take a rubber mallet and strike the bottom of the fuel tank a few times, until you hear the fuel pump turn on, even if it's only a second or two. Then try to start the engine again. Good luck!

No fire from coil- replace crank sensor, fuel pump relay , new spark plugs


If you have fire going into coil and not coming out than replace coil pack. They can become weak and will cause firing to be muted. Coil should read about 13ohms with an electrical tester when disengaged from the cars power supply set on 20+ohms. Anything less needs replacement.

Without a voltmeter and a wiring diagram, you're in a bit of a fix. But I would be wondering why the ignition switch isn't sending power to the coil primary positive terminal, and why it isn't causing the fuel pump to be turned on, too.
Is your check engine light on with key on? The computer should sense ignition is on and briefly turn on the fuel pump through the fuel pump relay, on just long enough to pressurize the fuel line to the injector. But no fuel or fire-you'd better start by checking if the ignition switch has power in and power out, and work your way to the coil.

My car won't start I have changed the coil fuel pump fuel pump relay and the Mfi relay I now think its the crank shaft relay but I do not know help me !


Sounds like maybe the main computer is bad. When you cranked the engine there is not any indication that it is firing. If you have changed the fuel pump and coil and it still wont even fire, the computer is most likely the cause. Even if the timming was off you would still get some indication that it was trying to start although it probably would not if the timming was off, but the fact it's not even trying to fire yeah that's my take.

No firing coming through the coil and fuel pump is not working both are related


It suggest checking the fuse and relay to the fuel pump. You might consider changing the coil. on a 6 cyl 4.0 or 4.7 the replacement part at PEP Boys should be E 239 BDW. About $130.00 bucks. Good luck Vicky.

How about the fuel pump...are you getting the fuel to the cylinders? Is the fuel making it through the fuel line through the fuel filter? Drop a few drops in 1 cylinder, if it fires, you have a fuel problem. Does it turn over? If not check out the motor starter!

Cranks well but won't start.


Looks like you got spark, and gas in the throttle body made it fire: nice work.
Sounds like your fuel pump is out or the wiring is not turning it on. One way to be sure is to set a spare battery near the tank and hot wire the pump with jumper wires. Or if you have a voltmeter check for voltage at the fuel pump connector while the truck is cranking.. If the pump is working and getting gas to the engine, see if the injectors are pulsing. A good idea to check fuel pressure if the pump is working.

It sure could be. But, first...by "won't turn over" you do mean it cranks at normal speed but won't start?
A simple test of the fuel pump is to stand by tank and listen as someone turns key to on. When first turned to on, your pump will activate for 2 or 3 seconds, pressurizing the fuel system, and then shut off if the engine computer doesn't get a cranking signal. Do you hear it come on? If not, then something's not turning your pump on. If you can hear it buzz on briefly, then maybe it's your filter. Another test: Spray a little starting fluid into your intake manifold (remove the big hose going into intake manifold) while someone tries starting it.If it doesn't fire and try to stay running, then it's probably an ignition problem. But if it does fire off, then you know it's a fuel problem-likely your pump or filter. good luck.
