You need to hook a fuel pressure gauge to it. It has to have 55 psi or it won't run. Have you checked for spark at one of the plug wires. I'm guessing low fuel pressure, fuel pump.

SOURCE: cant get no fire/replaced distributor

if i understand u correctly u replaced the distributor and cap if so i would start with making sure my pick up coil was installed correctlyand or replace it.i also would look at the possibility of it being a powertrain control module or neutral safety switch if this vehicle is equipt with one. hope ive been helpful

Try the light test.
1. Turn the lights on. The head lights should burn brightly.
2. Wiggle the battery cables and see if the brightness of the light changes.
If it does, then check the cables for looseness and tighten as needed.
If it doesn't, then go to step 3.
3. Turn the key to the start position and observe the lights.
Do they continue to burn brightly with no change.
Do they dim down considerably but, remain lit.
Do they go out completely.
If the lights do nothing and continue to burn brightly, then the problem is between the ignition switch and the starter. Check any fuse that has "IGN" in its description. If the fuses are OK, then you could have a bad ignition switch or a bad starter solenoid. Usually when a solenoid goes bad, you hear some kind of noise like a clicking sound. If you hear nothing at all, then check engine and body grounds before doing any thing else.
If the lights dim down but remain on, then the most likely cause is something mechanical like a bad starter or a blown head gasket. If you remove the starter yourself, then you can take it to a parts store and have it tested. There is usually no charge for this service . If the starter checks out OK, then remove the spark plugs and try to start the engine. (disable the ignition system by disconnecting power to the ignition module). If fluid comes out of one or more of the cylinders, then a blown head gasket is indicated.
If the lights go out completely, then the most likely cause is bad battery cables or bad starter solenoid if the battery is new. The cables can be checked with a set of jumper cables. The solenoid can be checked by placing a jumper lead between the large and small terminals of the solenoid and see if the starter works. If it does, then see if you can locate a fusible link in the wiring harness and repair as needed. If you need any additional information, then post a comment and I will get back to you as soon as I can. I hope this information is helpful and thank you for trying Fixya.com.

Engine light doesnt come on when key is turned on,cranks but will not start.no fire no fuel


Take to car to a diagnostic center, and they will attach a diagnostic machine to the car to see if it's the onboard-computer that's malfunctioning.

If the fuses are all OK, and the starter cranks the engine, but there's no firing, the diagnostic system will tell the tech what it is, there are various reasons there's no firing when the engine cranks,

Someone may say check the disable switch on the transmission, but if that's broken, the starter will not crank the engine.

Sounds like time for ignition switch. Don't hang a lot of trinkets and keys from your key ring. 2 keys at the most. I don't get the crank position sensor. I have never seen one go bad and has nothing to do with cranking the engine.

There is a starter relay in the vehicle and it is normally located under teh hood, in the power distribution box which is usually drivers side. When you say it won't start, do you mean it will not crank or it will not start. If the motor is turning over but not firing the problem is not the starter and is most likely fuel related. If it is cranking and will not fire, do a compression check on the motor. If you have zero compression on one or more cylinders then the problem is most likely a broken timing chain or belt. If compression is good and it is cranking over then you need to check the connections to the Distributor and the Crank and Cam position sensors.

Get fuel pressure tested, it should retain line pressure, may also be worth changing fuel filter as these get overlooked,I assume you mean that it does'nt fire first crank, If slow crank at first, check earth points ie chassis to engine, battery to chassis
