My vehicle is having issues, it will crank at normal speed but not turn over.
The car was in limp home mode and then we got contact cleaner and sprayed the MAF sensor. It went out of limp home mode temporarily and ran fine. High pressure fuel pump had good pressure, all good.
We had to go get a battery and left it for two days. The bonnet was left open and it poured with rain so the main ECU relay was sizzling as soon as the terminal was put on the battery. It just would not turn over to start.
We came back two days later after letting it dry and now there is no sizzling from the relay but there is no pressure coming from the h.P fuel pump?
I need help ASAP please!

Try resetting security system if no manual look online for your car on how to do it. You still may have a bad ecu, but you will need a mechanic to verify that so not to waste any money on an already good part. Besides the mechanic will have to program it to your car anyhow.
