van wont fire

Check for applicable mil codes. You can check those codes, yourself. Have a helper crank it, while you visually check for spark at the plugs, if you have spark everywhere, use a gage and check fuel pressure.

Are you saying at the moment, the starter won't crank? Check that the battery has a full charge, all battery connections are good. Check your security system, where applicable.

NO SPARK AT PLUGS, BATTERY IS NEW AND SO IS THE CONNECTIONS BEFORE I PUT IN THE PCM IT WAS TURNING OVER BUT NOT FIRING THEN I PUT THE PCM IN THAT I GOT FROM AT THE WRECKING YARD NOW IT WONT CRANK AT ALL NOTHING DIED

Kindly turn off the capital lock and put some punctuation in there so it makes sense. This can be read three different ways and is very confusing.

sorry so i took the pcm that i got from the wrecking yard out of my van and replaced it with the one that was in there before and now i get cranking but not starting

Any Applicable mil codes? You can check mil codes, yourself. You turn key just till the dash lites come on, no further, no crank. Cycle the key on--off, on--off, on, then the mil starts flashing, you count the flashes to get the codes. Your looking for two digit codes.

Did you check for primary voltage at the coil, engine cranking, dark green wire with orange tracer should be hot/voltage.

there are no codes not getting any voltage at the coil, nor from the dark green with orange tracer

The asd relay supplies voltage to several circuits, the coil is one. Usually, if the computer doesn't see the proper cam and or crank sensor it won't ground that relay. Any electrical part, if there is a problem on the wiring circuit, replacing the part won't fix it.

You should have got some type of code even if all clear. You might have to check voltage and grounds at computer?

checked the grounds at the computer notice that all 3 bolts are loose got to get bigger size hopefully that's it

Did you get it going?
