Check your plug wires they may be grounding out. If you just did a spark plug change make sure the wires were put back in the correct order. Also it could be that your timing is off.

Hi i have an 84 22r 4x4 that had the head gaskett and timing done about 3k ago and a tune up about 100miles ago and the other day it died on me as i was picking up speed in second and wouldn't start again...

If your backfiring most likely the timing is off. I would pull the cam cover and make sure all the timing marks are lining up when it is in Top Dead Center (TDC) Also on the older Toyota's there is a plug in the harness on the drivers side that has to be jumpered in order to set the timing correctly.

Now you can do the Fuel Pump

They seize up mechanically and fail

Did you drive with a fuel pressure gauge,
taped to the windshield

Got a good fuel filter

Looking won't help you

Always do some type of testing,
before replacing anything

Hard starting or will not start.once started idiols real rough

Check our Idler ( the black item right under he TPS at the trottle body) for function and clean them. If this don't works, check your fuel pressure (right cylinder bank, between 3. and 5. injector is a connector) you need 49 to 52 PSI. Check for stored trouble codes (ignition on, till bulb check is over), off-on four times, miles display will change in Trouble code mode. If there are any codes stored, you will get P and four digits, after finished you'll get "done". If there are no codes stored you'll get immediately "done" . If there are some codes stored, pleasy come back again with the numbers
