Fuel Pump Relay?
I know there is a relay that provides line pressure that comes on when the key is on, not working on my car. Trying to locate and figure out the problem, having to crank the car many times to start in the morning. Any help would be welcome. THX

You may want to check and possibly replace the oil pressure sending unit. gm had a lot of problems with these. Your engine needs to see oil pressure to fire. If the unit is out of whack you will get long crank time. I have seen this 5 times on 5 different gm products and this was the fix. Hope this helps.
