Engine light flashes when accelerating to speed over 65mph.


Consider a ground out (bad wire) to the coil pack? Or low fuel/no fuel pressure caused from a dirty/clogged fuel filter or bad fuel pump? A qualified mechanic can measure the fuel pressure and fuel output. Good luck.

Have a 1999 ford explorer sport 4x4, cranks want start. have replaced fuel pump, crank senser and cam senser, checked fuzes, replaced computer. doesnt seem to be firing


When you turn the key on you should beable to hear the fuel pump come on. Other than that you have a fuel pressure test port, looks just like a tire valve stem get a little probe press the valve after cranking fuel should come out strongly and not dribble out. If is doesnt seem to be firing your going to have check the coil pack for spark from the coil pack take one plug wire out and put it in a position that as you crank the vehicle you will be able to see spark jump or even hear give it a 1/4 air gap from its connection. If you dont have spark and your timing chain isnt broken you need to check for power the choice of tool is a test light.or volt meter. If you dont have either test tool we will go by sound when you turn the key on the engine fuse box has relays do you hear them click. That click noise will be fuel pump relay and PCM relay for power inpect those relays for corrode connections you mainly have a power problem and inspect for proper ground a missing ground can also cause the ECM to not fire the coils2_26_2012_7_32_43_am.gif

1989 Buick intermitent engine problem Buick Regal 3.1 V6 8th vin. T in nostart condition no fire @plugs no fuel pressure when cranking . Replaced : crank sensor ECM Ignition module ignition switch...


You did'nt say if you have had the car (Scanned) to see if the engine control Module has stored any fault codes. You say it runs 20 miles or so before it quits. After cooling does it alawys start back up? What have you been doing to get it running again? The ECM can warm up and quit. It'll get an Troblem code about though. The no spark at the time sort of removes the Cat converter overheating and the ingtion Module ( (the coils are mounted to it). Something getting too hot is likly. Crank sensers and cam sensers both wil do this the crank senser is on the back of the block just above the oil pan. The cam sewnser is underneath the power steering pump and the connector going to it is on top of the front valve cover on the passenger side. Crank sensers will not code and still be bad. Computers if they come back on ever they will code most any problem and the code name is Quad driver failure.

TWO DAYS AGO 94 RANGER (4 CYL) SOHC...STOPPED ON ROAD. CRANKS BUT DOES NOT START. HAS FUEL PRESSURE. CHANGED FUEL FILTER. CHANGED AIR FILTER. CHANGED ONE OF THE DISTRIBUTOR COILS...TWO SPARK WIRES WERE NOT...


If all the coils are giving spark now,then you moat likely have gas fouled plugs now,so change them out with new ones,all 8 of them.If you do not have spark on all plug wires,pull the timing belt cover,and align the cam shaft and the cam,to see if the belt has jumped.If It hasn`t,replace the crankshaft sensor.

No spark no FI pulse NO START


Check the ignition switch please. Had that on a 93 Ford that it was bad and the coil wasnt getting any electricity while the switch was in "start" position.
