Car cranks but wont start i replaced cam,crank sensors,and computer not getting any fuel pressure i checked fuel pump reset and its good,also replaced fuel pump relay its a lincoln markviii 1997

cranking speed has to be fast so make sure battery is well charged and in good condition
check that the stop solenoid is operational allowing the pump to pressurize the injectors
run the fault codes to check cam and crank position sensors
check for air in the fuel lines and pump--bleed system
check fuel level

auto shutoff relay controls both fuel and fire..the parts store can tell you for sure..

Do the basic tests. If it cranks good but won't start, have a helper crank it while you check for spark at the plugs. If spark everywhere use a gage and check proper fuel pressure and fuel injector pulse.
Any applicable trouble codes?

Get it diagnosed correctly. This is why we have 20,000 dollars of diagnostic equipment. If we were to guess I would of suggested the fuel pump.

This defineatly was not an alternator issue or a starter issue or battery by what your symptoms were.

You could have a failed computer or crank sensor or ignition module. Only testing will tell you what is not at fault and what is.

being 94' im sure it has high miles, cam and crank sensor common to fail over time do to wear and heat exposure. check the basic, make sure you getting fuel and sparks. fuel pump only work as long the engine is turning over due to the crank sensor sense the flywheel turning. crank sensor may be faulty. no sparks, check coil make sure is good and putting out 12v, auto zone can test it for free. good coil, than check cam sensor, cam sensor senses the cam turning and tell the ecu to tell the coil to disperse the sparks to the plugs. cam and crank sensors, there no way of testing it but replacing the unit unless you have the special equipment to test it; both is fairly cheap to replace, check ebay.

could very well be a faulty sensor, leaky vaccum hose, bad coil packs, needing of new fuel filter, spark plugs, wires.

Have you checked your fuel pressure to make sure it is good. You can do this with fuel pressure tester on the fuel rail.

Also check every cylinder for spark
If you don't have any spark, or very weak spark, you could have bad coil pack, module, or crank sensor.

You can remove one plug at a time, and place it back on plug wire, place it on top of engine block, have someone else turn motor over well you observe to see if there is spark.

Do you have a service or check engine light on? If so, I would have the engine codes read to pinpoint exact problem area.

Let me know if you have any questions or need further help

Check if you still getting fuel and sparks, two items need to keep the car running. Check fuses and fuel pump relay, if needing new relays go to the junk yard and get couple of them for nothing. Checking making sure you getting fuel and fuel pump working properly, unplug the the main coil wire to distributor so the car wont start we just want the engine just to turn over. under the hood, locate fuel filter, disconnect the line to or from it, wrap the bottom of the hose with old clothe firmly and to remember to point the house downward away from your face so it wont splash at you. and have a friend turn ignition over just like starting, see if the fuel come out with good pressure. if fuses and relay check out, your crank sensor may be bad, being 91' strong possibility. crank sensor send info to computer telling to send fuel to your injectors. For sparks, make sure you plug the main wire to distributor back. pull one plug wire and get spare plug, plug it and ground the plug and have a friend turn the engine over and see if you getting sparks, do not touch the plug, big shock. No sparks, check the coil if you getting 12v, if yes, than your cam sensor is faulty. The cam sensor work just like the crank sensor but telling the computer to send sparks to the distributor. Common for older European cars, crank and cam sensor tend to become faulty after years of service due to age and heat abuse.

Does it crank? Do you have any codes? Check engine light? Do you have spark? No spark check coil, and connections, also it would be nice to know what year it is. Get codes read. No crank check battery and starter. No codes or lights check crank position sensor, make sure your pcm is good after replacing your ignition mod you could have blown it if you did do it right. (engine computer) Check cam sensor if applies. Crank and cam could prevent it from starting and I know one I think cam controls pcm's fuel delivery on gm's

check the asd relay swap it with another like it. also check fuses and old car alarm if it had one.the cam and crank sensor will not affect fuel pressure. the cam sensor should not stop this car from starting. but the crank sensor will. good luck.

replace the crankshaft position sensor
