94 Yota Wont Start
I've got a 1994 Toyota Pickup, with the 3.0 V6, i just changed the alternator out, and now the truck wont start. After reading threads and searching, I am still unsure what my issue could be. I noticed the check engine light was on AFTER i changed the alternator out, but I have checked my fuses, nothing is blown, fuel pump is cherry, truck turns over but wont start. Any idea's? thought it could be the igniter. Anyone, please help.....

So?
Why?
And what does that tell you?
The CEL is your truck trying to tell you what is wrong. You need to listen. Read the codes.
Though most codes don't lead to a no-start. Put your timing light on each plug wire, then crank. If the timing light flashes, the plug is fired.
Just because your fuel pump is "cherry" doesn't mean it's doing anything. DON'T "crack" a high-pressure connection to see if you can spray flammable gasoline all over the place (if you do that, you must replace the crush washers.) Instead, replace the fuel return line from the FPR to a suitable container. Start the fuel pump by jumpering FP to B+. There is no spec, but I get about 1/2 liter/min. That will tell you you're getting fuel to the end of the rail.

Did you try the timing light on the plug wires? If no flash there, did you back up and put the timing light on the high-tension lead to the distributor? Did you run all the test for the distributor in the FSM? http://web.archive.org/web/201212070...12onvehicl.pdf

A timing light, a multimeter, and a tachometer, which may be part and parcel of the timing light, are tools you MUST have in your tool box. A jumper wire, for use in the test jack. Make it yourself. Terribly expensive, I know, but essential.
Then start in on wrenches, screwdrivers, and so on. Just my opinion.
