    First things first I have checked the coil pack, distributor, spark plugs and wires, all fuses and relays, and I still have no spark. I have a 1993 4runner with the 3vze 4wd automatic and I don't have any spark. I just recently got this truck and it would start just fine while giving it gas. So I replaced the fuel pump and fuel filter because the old one wasn't working at all as far as I know, and I replaced all fuel injectors because old ones were leaking. After doing all that I now don't have any spark and it won't start. engine cranks just fine and distributor will spin but no spark out of spark plugs. The previous owner did an EGR delete and the only place where I'm not getting any sort of voltage reading is from the plug that comes off the EGR and you put a resistor on. There's no power coming from that. When we were testing power from everything we got power from that plug for a brief second and the engine started but then we lost power there and it won't start again.

    The security system works just fine. In fact it’s constantly going off when diesel trucks drive past haha.

    I’ll check that chart and do another diagnostics on the system and get back with what I find out. Thanks.
