Hi steve perryman

Check for any broken or burned out fusible links from the starter. Then go back to the fuse box and by using a test light check all the fuses that power up the ignition and ECM, replace fuses if any are burned. Once your satisfied that the box is OK, take your test light again and look for power going into the ignition module and also the positive side of the ignition coil. Check all ground wires on the block to make sure they are not loose, broken, corroded, repair as necessary. Test the injector pulse width, hook up a node light to the injector plug, crank the engine and if the node light flashes quickly it means that the ECM is getting a signal from the module, hook up a spark tester also then while your cranking the engine, note if both node and spark flash.

post back your findings.
