My car kept shutting off every few minutes while driving so I changed the fuel filter but it still keeps shuting off while driving. I also replaced hoses. checked spark plugs and changed timing belt. any ideas what it could be.
After it kills, pull a plug wire and check for spark. If it has spark, check for fuel. I can't remeber where the service port is on the F.I of a Neon but it'll look like a tire air valve cap but a little larger. It''l be on the fuel rail or line somewhere under the hood.
Take the cap off and depress the valve. If fuel doesn't squirt out (not drip), you're losing pressure. Neons were bad about fuel pumps so it MIGHT be this. They run a little over $200 for just the pump. I had a retail unit that kept doing this due to fuel deposits from Ethanol. It kept clogging the "filter" sock in the tank. After it set a while the stuff would sink back to the bottom and the car would start back up.
I have a 99 dodge neon my fuse to my fuel pump would burn out and stall every ten minutes it took me 3mechanics and it coste 466.00 to fix . They found an electrical short next to the o2 sensors that were getting to hot and melted all 4caes together
I'm not sure how to test it, but it sounds like the fuel pump.
