having trouble with my mk3 astra let as it wont start and it seem that the fuel pump isnt kicking in when i turn the key.

ive checked:

spark
compression
the fuel pump inself wired straight from the battery
checked all my wiring from the conversion
changed the fuel relay because it seems that the rubber was melted?

any ideas what else i should check?

Correct. I thought maybe the loom was lacking power ie switched feed or main + but if it runs its a relay/wiring/ecu fault

Get the mutimeter out and start checking it all, is there a feed from the fuel pump wire at the ECU whilst your cranking/running?

Sorry to message 14 year later 🤣 I’ve a mk3 C20let and I’ve exactly the same problem as you. All fuses have been renewed. Which one was knackered for you? Was the car cranking as mine isn’t?
