Hey guys and gals, thought I could get some advice for my 98 Neon. So far this is what's up with it: About 4 days ago it choked out coming home from work. It didn't limp home it just stopped, I checked the fuel pump, batteries, fuses(not the relays), and then the lines. This is what I am thinkin' so far; The codes tell me I have an 11, so it could be the Cam or Crank sensors. My question is this: Aside from general advice which would be much appreciated, how easy are the sensors to replace? I feel really dumb since I am an Army mechanic and could rip the guts out of a Humvee, but this is kicking my butt!

 

When you turn the key, what happens?

 

I can hear the fuel pump, then it cranks but will not turn over

 

Have you checked the fuel pressure at the rail? Should be about 49psi.

 

Many of the dodge codes can be broken down further if read on a proper OBDII reader.(see below)
[ul][*]11 - No crank reference signal at the Powertrain control Module (PCM).[*]11 (P1390) - Timing belt skipped one tooth or more.[*]11 (P1391) - Intermittent loss of Camshaft Position Sensor (CMP) or Crankshaft Position Sensor (CKP). [/ul]

So have the codes read it could be as simple as a sensor or as bad as a damaged or broken timming belt.

The camshaft sensor is on the transmission end of the head. just unplug the wiring and remove 4 small bolts if its the same as the 1995. The crankshaft sensor is behind the alternator, I've never done one of these but it appears to be mounted with a single bolt.

 

Thats only four bolts on a SOHC head and two on a DOHC. The sensors are fairly easy to replace about 10 to 15 minutes to replace each one. Invest in a Haynes manual, its only $15 and it tells you where everything is.

 

Thanks for all your help, can someone direct me to a good online parts store?

 

Have you looked at the timing belt yet??
