Thanks for your help...
I have a 1990 toyota truck, won't start, losses power
What is your question?
won't start, it has taken longer and longer to catch when starting... but turns over just fine... last week It did't start so I checked wires and connections.... un plugged ignition coil and plugged it back in... then it started. it lasted about a week then the same no starting problem again... I did the same thing un plugged coil and plugged it back in, and wire going from coil to distributor, and clean battery cables... then it started after a few tries... then as I was driving about 5 minutes, it lost power so I pulled over and let it sit over night. Next morning, It started , then after 5 minutes or so, lost power going up a small hill.
I had it towed, but now I must decide to take it to toyota to diagnose, or to trouble shoot, myself, and start replacing parts, like the coil, on my own one by one. I don't have a lot of tools nor experience,except call support from dad, and a truck manuel and volt meter.
RepairPal Certified shops can diagnose and repair your 1990 Toyota Pickup. They provide transparent pricing with a minimum 12-month or 12,000-mile warranty on repairs and services.
My first guess would be your fuel pump is failing. It can be difficult to check fuel pressures w/o the right tools - and dangerous to try to check for fuel w/o the tool. It's also possible the fuel filter may be restricted. If you want to replace the filter first, might be a good idea - its fairly easy to do and the part is inexpensive.
I wacked on Igniter modual, which is next to the coil on my truck, and then it started... I drove it home and then replaced the part, and now it starts, and seems to be ok now. I think it may be wise to have the fuel filter checked like you said... also there is 119, 000 miles on it, maybe time to change timing belt.
thanks for your advice!!
Have you pulled the spark plugs for inspection yet? Keep them in order of cyl. removed from , that may be helpful for later diagnosis. V6 should be NGK or NIPPONDENSO platinum may still have sticker on front of timing cover.Check all hoses to and from mass air flow meter , check the air flow meter itself for debris. Check the air filter. When it loses power , is it a smooth loss of power or is it rough/ mis-firing?
