Original, you should check for injector pulsate and fuel pressure. If either of these are not working, so there are some specific diagnostic paths to follow. If information technology is only trigger off you are wanting, check wholly the fuses.
Make a point to check them all as we ne'er know if one fuse supplies power to another. If all the fuses are good, check for power and soil at the firing mental faculty. If you don't have power or ground at the module, you will need to trace the wires back until you find the bad connection. Deterrent harness connectors and fuse blocks before you start up lacrimation into a harness.
I mentioned the injector beat first. This is advisable tested with a noid light. If you don't have injector pulse, the most common cause is a nonfunctional crank detector. This can be checked with a digital scanner. If you don't give birth a crank signal on the image scanner, hopefully there is a code to guide the diagnosis.
