86 toyota 4runner wont stay running
2days ago it started chugging like water would be
in tank. The tank was on ( E) I put high test gas in
and gas treatment no change. I drove around the
parking lot chugging and backfiring. Then truck
starts looseing gas power . I left it sit there in
parking lot . next day I tried to start it . truck starts
2sec. Then nothing . I changed fuel pump . no
change . I changed fuel filter no change. Each time
I did something I tried to start truck again 2sec .
run then nothing. I'm thinking injectors
2 seconds sounds like the security system somehow went into full active mode. But I didn’t think an 86 had one unless some aftermarket unit was installed. Did you check the relays?
I don't know where any relay is.
Found the relay next to fuse box but how do you know if that's working
Got it Engine stalls. One of the first symptoms of an issue with the fuel pump relay is an engine that suddenly stalls. ... Engine does not start. Another symptom of a faulty fuel pump relay is an engine that does not start. ... No noise from the fuel pump. I wondered why I stopped hearing my fuel pump buzzing. Lol
Thank you from Concord Nc.
I hope it's the round one. It was in the fuel relay spot I seen some online that are square.
Question what if my injector relay is so hot is it bad or just not working . And fuel pump relay is not hot.
Fuel injection relay will run warm but not hot, if it is hot then you could have a short in the injector wiring or injectors that have too much resistance. Same with the fuel pump relay, warm but not hot, if it is hot then again wiring issues, or a bad fuel pump. As I'm not sure of the build date of your rig about the relays but Toyota did use round relays some years back. Sorry about taking so long getting back, I had shoulder surgery 1 week before this Covid 19 thing hit, so we have been doubly careful and I just couldn't type.
