Well, was going to suggest that there's air in the fuel lines. But the HG issue would cause your symptoms as well if it's as obvious as you say.Got the new assembly put in and cleaned the fuel tank out pretty well. Actually looked good when I was done. Got the vehicle started twice for about 3 seconds then it died. Now it won’t turnover. Charged the battery and still won’t turn over, but all the lights show up and I can hear the fuel pump running when I turn the key. Assuming the starter is bad or knocked out of place. Anyone ever had that happen?
Also another note I think the head gasket is blown. Changed the oil and a decent amount of coolant in the oil pan. Just hoping it’s not cracked block but the plan was to rebuild the engine anyway. May just purchase a rebuilt one if it’s cracked block.
If the engine turns over, the starter is working correctly imo.
