My 2000 ford focus wont stay on idle. hard to start, seems like rich fuel mixture


Did you check to see if you have any codes in ECM or an engine light on ? If it's been sitting for that long, might have other issues which cause this problem.

This morning my 2000 Z71 Silverado 1500 had trouble starting. It took about 3 attempts, then started sputtered and die. On the 4th attempt I pumped the gas, held the engine rev about 3500 then it was fine....


May be a problem with the mass air flow sensor located on the air cleaner assembly. Dust particles sometimes collect on the very small resistors on the MAF Sensor. Buy some electronic dust spray you use for computers and spray the resistors. Be carefull not to touch them, they are very sensitive. Thanks.

2000 catera cold start idles rough and dies. After a few times it gets warm enough and runs smooth as silk.


Did you have battery disconnected or dead recently?

Try to place ignition in run without starting engine for 3 minutes (shut off all accessories and lights etc..). Then shut it off and then start it. Should relearn the idle.

If this doesn't fix the problem, unplug the MAF sensor, if it runs fine with it unplugged, its the MAF sensor.

Exactly what happened on my wife's 01'.

My 2000 nissan maxima dies about 4 or 5 times when i first start it in cold weather


If you're getting check engine light take it to Autozone and they'll read the code. On mine the Mass Air Flow sensor was the culprit. Engine codes suggested MAF, manifold vacuum leak, coils, injectors clogged. Mass Air Flow sensor cleaner did nothing. Ultimately I replaced each coil ($75 per cyl) but still conked out like yours. MAF cost $300 at the store, but found one online $97 took a gamble and replaced in 5 minutes. It really made a difference.

2000 Crown Vic cranks but won't start.


Check the fuel pump reset switch again, if it is popped back out then replace that little switch in the trunk, any ford one will do. it works off a magnet and a bearing to close the circuit for the fuel pump. easy fix.

2000 ford focus runs rough when I unplug the mass air sensor, but won't start when the mass air sensor is plugged in. How do I fix this ?


The MAF itself is probaly defective. First check if the filament is dirty, and try cleaning it with MAF cleaner in spray bottle. The way MAF works is that air current cools a heated element resulting in lower resistance. This minute change is further amplified by the circuit in the MAF sensor and fed to the computer. I have never tested a MAF sensor, but I can probably test one. Since the engine don't even start I would probably use a fan, and with the ignition in on position I would probe for voltage changes, that changed with the amount of air rushing through it. There should be a supply voltage, a ground, and the rest would be in series with other sensor, then one would be the input to the computer which varies in value with the amount of air going through.

2003 Ford Focus will not idle


try cleaning the MAF Mass Air Flow sensor element wire in tube with a toohtbrush and carb cleaner carefully. It gets coated with a film. It is in air inlet hose and has a wiring connector on it. Then drive for 15 minutes so it can learn the clean MAF sensor. Is check engine light on?

Removal
  1. Remove the air cleaner outlet pipe.

2000 ford focus new feul pump new feul filter new feul pump relay car still want start


Try the crankshaft position sensor. Sometimes they get covered in clutch dust and the sensor cannot determine No1 cyl. and then it will refuse to start. Sometimes they go faulty as well.
