Car Forum / Dodge / Dodge Cars / December 20081993 Dodge Caravan has no fire...
Hello, We already replaced the coil and the crank sensor and still no spark. We don't want o replace to much more with out some idea. The Haynes manual seemed to point to these two parts but we are stumpted at this point. Any ideas greatly apprerciated! > Hello, > > We already replaced the coil and the crank sensor and still no spark. > We don't want o replace to much more with out some idea.

The first thing I would do is to try and pull diagnostic trouble codes, by turning the ignition on, off, on, off, and on, just to see if the engine computer (SBEC) is powered. You should at least get a code 55(end of codes). If you get nothing, then I would check pin # 3 on the 60 pin computer connector to make sure it is getting 12 volts. The 1992 computer was powered by a fusible link that tended to burn up just because of old age. I would assume the 1993 is the same way, or possibly they went to a fuse setup to power the computer. Thanks Steve...I'll try the code trick and see what happens. Do I need to buy one of those code translator devices since we can't drive the van anywhere? > Thanks Steve...I'll try the code trick and see what happens.

You could buy a cheap code reader, but with a 1993 you should be able to to the "key dance" by turning the ignition to "on" (not start), then off, then on, then off, and then on and leave it on. The check engine light will then flash codes. The codes are always 2 digit codes. Example blink * blink * blink ...pause blink * blink - whould be a code 32.

Neither of these are significant in your case but they tell you the computer is powered, so it's fusible link (or fuse) is OK. Have you done a simple spark test by removing a plug, grounding it as someone turns the engine over, and seeing if you have spark? Or sprayed a TINY amount of starting fluid, or carb cleaner into the throttle body to see if it's fuel starvation related? > <cudacud...@yahoo.com> wrote in message > [quoted text clipped - 32 lines] > TINY amount of starting fluid, or carb cleaner into the throttle body to see > if it's fuel starvation related? Steve, I saw no spark jumping from one of the SP cables to the plug when I held it about an 1/8 from the plug tip. I even touched it with my finger to make sure there was no spark. I'm kind of baffled at this point. id check ohms on each injector.a bad injector can scramble the puter drivers. sorry i dont remember what reading should be but it may be obvious if ones dead.. ---------------------------------------------------------------- http://www.minibite.com/america/malone.htm On Dec 13, 4:14 pm, cudacud...@yahoo.com wrote: > Hello, > > We already replaced the coil and the crank sensor and still no spark. > We don't want o replace to much more with out some idea.
