94 Caprice will not start((((HELP))))!!!
I have a 1994 Caprice Classic that will not start. For a couple months it was taking a while to start. when i would start it would turn and turn and turn until it would finally start. one morning i got into my car and it turned turned and turned and never started again. I am going to tell everybody exactly what i replaced so far, The fuel pump, fuel filter, fuel pressure regulator, ignition coil, ignition control module, distributor cap and rotor along with having the timing chain changed, spark plugs and wires computer chip and knock sensors. Any more idea why it will not start?

the distributor on these are very sensitive to coolant getting into them. this is because this is directly below the water pump weep hole. if the water pump leaks at this weep hole which does occur from time to time it will get into the distributor especially if this distributor has not been modified or updated with the venting of the 1995-1996 model year. why was the timing chain replaced ? who had /came up with that idea ? the other item which has caused this problem is the battery feed wire/connection to the underhood fuse box. this connection was not properly secured when this vehicle was built. over time many have had this melt and cause this no start problem. big red wire to the fuse box at the fuse box...... |

The repairer is an idiot or a crook . timing chain on this is not an issue with this vehicle. this has a steel timing chain. the chain could be worn if not properly maintained, but not stretched. also what timing marks ,,,,, there are none. timing is not adjustable. WE ARE TALKING ABOUT THE LT1 ENGINE CORRECT? |

Re: 94 Caprice will not start((((HELP))))!!!
Thanks. Funny though, the mechanic said that my car does not have a crank position sensor... SMDH. He said that was the reason for replacing the knock sensors because they do the same job as the crank shaft sensors would do....This is getting more strange by the minute. i mean its only a 94 Chevy...i'm not a mechanic, but how much easier can it be?

Re: 94 Caprice will not start((((HELP))))!!!
Hmm maybe people are at work, ( we hope) and do not have the time right now? Retired here, so let's see what we can do. Someone has to trace down the cause of no spark, simple, it is an ignition problem, from here we cannot do onsite diagnosis, none of the work done relates to no spark other than the pcm, coil and ign. module, Inside the dist there is also a pick up. And of course wiring connections.. The knock sensors have no affect on starting, J Cat's advice seems to sum it up.

your vehicle 1994 does not have a crank sensor ...my 1996 LT1 has a crank and cam position sensor. these provide a more accurate timing/control with the opti distributor computer controlled system.. you 1994 though not as accurate as the 1996 is still a very accurate timing system. when the engine rotates the cam connected to the opti distributor tells the engine where its at. so no signal no start... this is where the opti can cause no spark if damaged..
