Did you only do the fuel pump relay? Or did you also do the fuel pump? Have you done a fuel pressure test?The fuel injectors should be getting power to them all the time and the engine computer gives them a switch to ground to pulse them. You can use an LED test light across the connector for the injectors while somebody crank the engine over and see if the test light pulses if it does and you're not getting any fuel out, then you don't have any fuel pressure.If I've answered your question your satisfaction please remember to accept next to my name is ***** ***** the only way the site will compensate me for my time. So please don't hesitate to ask if you have any further questions, you can continue to ask follow-up questions even after hitting accept.
