We put OEM coils, spark plugs, starter and ele ctronic ignition harness-got 1320 cleared We put new purge volume control, cleaned all hoses and parts and put new purge canister on-got 1445 cleared There are no codes showing now and car still just cranks and won't start still, battery is good,new fuel filter desperately need this car running.Any ideas? She's a 97 Maxima SE manual

 

First place I'd start with is SPARK.

 

We have spark, thinking maybe Crank sensor or camshaft sensor??? thanks

 

Could be those sensors. There are 2 crank sensors. Is fuel getting to the filter and then past it to the injectors? No other codes?

 

There's no other codes, sorry there's no spark sprayed starter fluid and no start

 

Crankshaft position sensor has oil on it,is that normal?

 

If you've got spark, that rules out a lot of other things.

Got Milk?

I mean gas, after cranking and no fire, you should have gas on the plugs or at lease fumes coming from the plug port.

 

If you have an upper oil pan leak then oil on the crank pos sensor is normal. Spray electric cleaner on it to clean it. If you have no spark then you have other problems. Electrical problems are the worst. These cars have a lot of grounding problems. Make sure cables are well grounded.

 

By chance, has any transmission work been done lately?

 

No transmission work done, it's in good shape, cleaned crankshaft position sensor and getting ready to put back in

 

Sorry it took so long to get back but we ran into a few problems with wiring, got that fixed too. I ordered all three sensors and all three are installed and now it's barely starting and at a VERY rough idle with a backfire and dies. It wouldn't start at all before but now what?any ideas?

 

Peach 97: we missed some backstory. Presumably the car was running when you added those parts / cleared those codes - is that correct?

but now it's not running at all? What happened, again ?

is the gas old ? What's the measured fuel pressure ? How do you -know- you have spark (not just because you replaced those parts - right?)

lots of help available here here but we only know what you tell us

 

Are your coil plugs crossed?

 

Are you sure you have fuel pressure? Like enough to push through the injectors as required for the range of RPMs under load?
