The truck starts, idles, you can rev it up but once you put it in gear, the fuse blows. We thought it may be the fuel pump so we replaced it but it keeps happening. This is a 95 S10 pick up with a vortec cmfi.
Any help would be appreciated!

Reason: forgot year and corrected vortec info
Is yours VIN Z or W? The 20A ECM Ign fuse 10 supplies power to the ICD module, fuel injectors, CKP sensor, and PCM or VCM. A wire with missing/worn insulation shorting to ground as the engine shifts, maybe?
If the spider was going would that cause the fuse to blow too?
It never gets passed drive. The last time we tried we put it in drive gave it a little gas (the truck is currently stuck on a hill) it stayed running until it was given more gas to pull the hill. Then it popped....then back to square one.
I don't see how. Anything funny in the fuel injector circuit would have it running weird. Unless, there's a short in the wiring. Did you ever try moving it in the dark. If it's a short in the wiring, it should produce pretty good spark to blow a 20A fuse.
