have checked timing belt, in time. Ohmed the 2 pickups in the distrubitor and they review in spec. One more site proved two relays in the fuel pump circuit, an initial the EFI relay is pulling in when the key is in the run position. If i am looking in ~ the exactly relay (the various other site referred to as it the "circuit interrupting relay") in the passenger absent panel med dimension black relay just to the right of the ECU. Ns am getting an extremely frustrated at not being may be to find out what things can keep the CIR native pulling in.
The car was no running and also I replaced the fuel pump. That started and also ran good. After ~ the second start that shut turn off from 2,000 rpm's and also I have checked and rechecked everything I have the right to think of. Over there is no strength to the pump when you rotate the crucial run for the 2 seconds. I additionally checked the distributor pickups with an ohm meter and the ohm okay. Also ohmed the coil and also it look at okay. Checked voltage in ~ the primary of the coil and no reading once the crucial is in run or start. Perform you understand where I can find a schematic because that the car? i am pretty great at wiring and troubleshooting need to know exactly how the circuit works.

few of those execute not power the fuel pump till they room cranked.Okay, we have to start from the beginning. I can aid you here. Do these tests and also post the results and we will go native there.All "crank, no start" conditions are approached in the same way. Every engine requires certain functions to have the ability to run. Several of these functions rely on certain components to work and some components are part of an ext than one duty so the is essential to watch the whole snapshot to be able to conclude anything around what may have failed. Also, these features can only be tested throughout the failure. Any other time and also they will merely test an excellent because the trouble is not present at the moment.If you approach this in any other way, friend are simply guessing and also that only serves to change unnecessary parts and wastes money.Every engine requires spark, fuel and also compression come run. The is what we have to look for. These room the basics that should be tested and will provide us the information required to isolate a cause.1) Test for spark at the plug end of the wire making use of a spark tester. If nobody found, examine for power supply top top the confident terminal the the coil through the an essential on.2) Test for injector pulse using a small bulb dubbed a noid light. If none found, examine for power supply at one side of the injector with the key on.3) usage a fuel push gauge come test for correct fuel pressure, also noticing if the press holds when key is close up door off.4) If all of these things examine good, climate you would need to do a complete compression test.Once girlfriend have determined which that these functions has dropped out, you will recognize which device is having the problem.
