heres another stumper for you all, my truck wouldnt start

, so i replaced the distributor cap, rotor, and all 5 cords coming out of the d-cap, i also replaced the coil, the only thing left is the igniter, ive never even heard of an igniter

, neither have most of the parts places around here that i talked to. I was quoted 7.99

last night after my truck got starnded in the middle of nowhere

, i went in today and they said it was gonna be 398.99

, i was pissed

, the guy there took it apart and looked at it, he had no idea what he was looking

for but wanted to look anyways, a few more parts shops down teh road soembody told me it was no good because it had been taken apart

. Its a Nippondenso igniter, part number 131100-2561, 12 volt. I have an '81 Chevy LUV, its got an Isuzu motor, and the igniter is a Toyota product

, so all the dealerships that I went to told me to go to another one, and none of them can help me

, if anybody has any ideas as to what I can do that would be great, the junk yards around here don't have a lot of love, or luvs, so im kinda screwed that way, unless i can get the part from another truck, im thinking maybe an Isuzu PUP, but i dont know what year or anything, these luvs are a bitch to work on arent they, and where is the fuel filter located

, i bought one, but dont know where to put it on at, anyways, if anybody knows where i can get a new or used iugniter, how i can test my igniter to see if its still any good even, or if you can tell me what could be wrong with my truck, anything would be helpful, thanks
