Does the car have gas in the tank? May sound stupid but my friend kept telling me his Charger wouldnt start. I told him to check the lines, etc but he was hard headed so he loaded it up and brought it to my house.
The pump was pumping fine when I ran a hose to the can. I took the line loose at the rear and blew through it. No clogs.
So I pulled the sending unit. I had it almost all the way out before I saw a little bit of dampness. I put it back together, poured 5 gallons of gas in it and fired it off.
He had several other small things like timing that was off, vacuum leaks,etc that I fixed but within 2 hours of me starting on it, the car ran like a top.
I called him and told him 9 out of 10 Dodge cars run better with GAS in them. He said,"That car had gas. I put a gallon in it." A gallon? I told him that wouldnt be sufficient for a beast. LOL
Start at the pump and work your way back.
My Valiant had been sitting for years when I bought it. It started at first but then wasnt getting gas. The front to rear fuel line was completely clogged.
