Make sure the spark plugs are properly gapped (this will cause misfires). Replace all spark plugs wires!! Insure there is no oil inside the spark plug chamber.

How do I find the cause of not getting any fuel to the engine?


How about a Vehicle & Motor & test results

Scan Tool Data would help

Misfire Counts,Fuel Trim,vehicle maintenance history

If you have a Chevy Blazer- the fuel pressure regulator
& spyder are under the intake & could be the problem

Lots on the internet on that & video

You have OBD Codes-what are they? Google them

Don't see how you would think changing the spark plugs
would be the only issue

START THE ENGINE AND LIFT THE IGNITION WIRE LISTEN FOR SPARKS.IF ONE OR MORE CYLINDERS DON'T CHANGE THE WAY IS RUNNING ,YOU GOT THE BAD CYLINDER. LOOK FOR BURN MARKS ON THE WIRE(BLUE/WHITE SPOT)IF SO REPLACE THE WIRE.SOME TIMES VALVE COVER LEAKING IN THE TUBE. REPLACE VALVE COVER GASKET,BLOW THE OIL OUT BEFORE REMOVE THE SPARK PLUGS.REMOVE THE SPARK PLUGS AND INSPECT THE ELECTRODE.GOOD ELECTRODE WILL BE WITH SHARP EDGE ,IF ROUND OR LIKE CONE REPLACE WITH DENSO OR NGK ORIGINAL EQUIPMENT . REMOVE THE DISTRIBUTOR CAP AND LOOK FOR OIL IN THE CAP. IF OIL INSIDE REPLACE DISTRIBUTOR. IF NO OIL INSPECT THE CAP AND ROTOR FOR THICK WHITE DEPOSIT OR ROTOR FOR BLACK BURN MARKS. REPLACE CAP AND ROTOR.IF EL.SYSTEM IS OK SPRAY CARB CLEANER ON INTAKE MANIFOLD AND LISTEN FOR RPM CHANGE.IF CHANGE THE RPM REPLACE MANIFOLD GASKET.

Hi, I have a 1997 Porsche 993. Motronic 5.2 M07. I am getting these fault codes 1) 62 misfire emissions-relvant 2) 51 Cylinder 2 misfire emissions-relevant) 3) 54 Cylinder 5 misfire ...


misfire :-------- try checking your 02 sensors /fuel pump and filter.

for 51 cylinder misfire :---
Change the coil. Period. Very easy to remove from the vehicle if it's a 4 cyl. Follow that spark plug wire from the spark plug to the other end. What it's attached to you should replace
for 54 cylinder 5 misfire :---First you have to eliminate the most obvious problems, like spark plug and spark plug wire. If you replace those and you still have a misfire, then it's a good idea to look for a vacuum leak in the intake manifold

Misfire after tune up


Since you have a misfire, the fuel in that cylinder isn't burning. Are you sure you have the firing order correct. Also try using one of your old plugs and wire for that cylinder and see if it works. If you only checked for spark at the wire, you might just have a faulty new plug- it happens.
