Just wondering why my truck doesn't start in the morning?I've already changed fuel filter, spark plugs, spark plug wires. But it only does it in the early morning come 9:00, 10:00 it will come on but it takes a min. It also backfires when trying to turn over. Thank you

Hi there,

Start with a scan to check for any set fault codes, when it wont start check for spark & injector pulse, if these are OK, I would be checking the fuel pressure next.
