MattyC. If you have a multi meter, the knowledge how to use it and the willingness to do so. I maybe able to help. First send me the model number off the tunnel so i can ensure we have the correct year. The 92, 93 and 94 up are all different the way the power the ECU. There are some things you can check right away. You need to have a perfect battery, check the voltage, check your compression. Do you have a fuel pressure tester? Just because the fuel pump runs does not mean it can supply the correct fuel. We will have to check fuel pressure and flow.
