98 neon no start/ misfire
I have a 98 neon 2.0 dohc. wont start or stay running, runs rough when it does start. I have spark at all 4 plugs, primary side of the coil are at .3-.4ohms each, secondary sides are 11.8K. i have power to the center terminal in the coil plug. Fuel pressure is at 50 psi with the key on or while cranking. Any help or suggestions would be greatly appreciated, as this neon is a daily driver!
It shows p300-p304. checked all the injector wiring, firing fine. got spark, got 50psi to the fuel rail. map sensor 28-29hg key on, tps sensor reading 0-80%, can't move the EGR valve by sucking on the line, sorry I don't have a vacuum pump, EGR seems to hold vacuum, coil tests .3 -.4 ohms primary, 11.8k secondary, got spark all 4 cyl, I checked w a spark tester, pulled the plugs, checked gap, it was at .30 I regapped them to .35, newer NGK plugs, plug wires seem fine, Car will fire once, then nothing. Any ideas? I'm thinking EGR is stuck open? EGR transducer gets warm, clicks if U unplug it w key on. Any ideas would be greatly apprecciated!
