have checked timing belt, in time. Ohmed the 2 pickups in the distrubitor and they read in spec. One more site verified two relays in the fuel pump circuit, very first the EFI relay is pulling in once the an essential is in the run position. If i am looking in ~ the correct relay (the various other site called it the "circuit interrupting relay") in the passenger absent panel med size black relay just to the best of the ECU. I am getting an extremely frustrated at not being able to discover out what things could keep the CIR indigenous pulling in.
The auto was not running and also I changed the fuel pump. It started and also ran good. ~ the 2nd start that shut off from 2,000 rpm's and also I have actually checked and also rechecked everything I deserve to think of. There is no power to the pump once you turn the an essential run for the 2 seconds. I additionally checked the distributor pickups with an ohm meter and the ohm okay. Additionally ohmed the coil and it watch okay. Confirm voltage at the main of the coil and also no reading as soon as the vital is in run or start. Perform you recognize where I could find a schematic because that the car? i am pretty an excellent at wiring and also troubleshooting need to know how the circuit works.

few of those execute not power the fuel pump until they space cranked.Okay, we have to start native the beginning. Ns can help you here. Carry out these tests and also post the results and also we will certainly go native there.All "crank, no start" problems are approached in the very same way. Every engine requires certain functions to be able to run. Some of these features rely on particular components come work and also some components are component of an ext than one function so it is crucial to view the whole picture to have the ability to conclude anything about what may have failed. Also, these functions can just be tested during the failure. Any other time and also they will simply test an excellent because the difficulty is not present at the moment.If you approach this in any other way, girlfriend are simply guessing and that only serves to replace unnecessary parts and also wastes money.Every engine requires spark, fuel and also compression to run. That is what we have to look for. These space the basics that must be tested and will provide us the information required to isolation a cause.1) Test for spark at the plug end of the wire using a spark tester. If nobody found, check for power supply ~ above the optimistic terminal of the coil through the vital on.2) Test because that injector pulse utilizing a small bulb dubbed a noid light. If none found, check for power supply in ~ one next of the injector through the key on.3) use a fuel pressure gauge come test because that correct fuel pressure, additionally noticing if the push holds when crucial is closeup of the door off.4) If every one of these things check good, then you would should do a finish compression test.Once friend have identified which of these functions has to reduce out, friend will recognize which mechanism is having actually the problem.
