Question
Was driving down the road pulled upi to a stop sign and when i went to pull out the van just died checked for fire there was none and then checked for fuel. There was none.Then i checked the fuel pump and it was working . So i went to the auto shut down relay replaced it still nothing. Someone told me that the only thing left was ecm or (pcm) Please help

Answer
Hi Anthony,
You didn't tell me the year or the engine. Let me know that if/when you reply. The reason for no spark, with the fuel pump still working, could be the spark coil or one of the two engine position sensors (crank or cam). If you have a pre-96 van you can check for fault codes in the engine controller which would help with the diagnosis.
On the spark issue, please re-verify whether you get no spark or spark for 1 second or so when you do a 5 second crank. This is of diagnostic significance for me.
Reading out the engine controller memory for fault codes is the first step. Try using the ignition key: turn it "on-off-on-off-on" and leave it "on" (doing this quickly, no longer than 5 seconds). By "on" I mean just the normal position when the engine is running, not the cranking position. The 'check engine'light will remain on when you leave the key in the "on" position with the engine still not running. But then watch the 'check engine' light to begin flashing, then pause, flashing, pause, etc. Count the number of flashes before each pause and keep track of the numbers. Repeat the readout and verify the counts are correct. Then group them in pairs in the order that they came out, thus forming two digit numbers. You may notice that the pause is shorter between the digits of a given number, and longer between the numbers themselves. Then send me a 'follow-up' question telling me the results of your readout. By the way, 55 will be the last number (two groups of 5 flashes each) and that is the code for "end of readout".
I have the troubleshooting manual for several engines and we can look up the possibilities of what is wrong based upon what fault codes you show. There is also an essay on fault codes at the site:
http://www.allpar.com/fix/codes.html
which gives the meaning of the code numbers. But then you need to get specific info for what exactly might be the diagnostic tests or parts to replace to complete the repair. Let me know the codes and I can give you some direction. If there are no fault codes then the problem could be a spark coil pack issue. Don't crank it for more than 5 seconds. If you get spark for 5 seconds then that is o.k. and we will have to look further. If you get spark for 1-2 seconds or not at all, that is relevant to know.
So write back with the results.
If you have a '97-on van you may have to have the codes read out at a dealer or a parts store (Autozone, I have been told) which might do it for free.
So don't rush out and buy a PCM yet.
