So I searched and searched and couldn't find this issue, forgive me if it's there and I didn't see it :/
I have a 1988 XJ 4.0 that I just swapped a 1990 XJ 4.0 engine and AW4 tranny into. It's not starting, it will crank but, no start. On top of that, I have a very prominent buzzing sound coming from my fuel pump relay that wasn't there before. This buzz starts when the key is turned to "ON" and lasts a few seconds. After this, I crank the engine and at that moment the buzzing continues until I return the key to "ON" and after a few seconds it stops. I replaced the CPS earlier after I found that I had no spark. Unfortunately, I don't have anyone here anymore to help me check for spark.
What I've done so far:
- Replaced grounds(new): firewall to head, battery to block, battery to fender and, added ground to alternator housing.
- Replaced Alternator(new)
- Replaced battery(new)
- Replaced battery terminals and cables(new)
- Replaced starter(used)
- Replaced CPS(new)
I am not sure what is going on or even if the buzzing has anything to do with my start issues :banghead:. Any help is greatly appreciated! THANKS!
