Repairing is a lot easier than replacing, check all the connector ends, esp engine bay, i had to replace the majority of mine due to failed connectors and fiat rotten wire, get a multimeter or simple electric tester and start at the prob ( sparks) and work your way back, also helps if you can read the haynes manual wiring diagrams, which i learnt in the mornings on the bog, does the fuel pump buzz, (prime) but no spark?
