every time it starts it will run for 1 minute and 24 seconds unless i spray fuel down the carby. proves very difficult to drive it down the road..

from experience, I believe that the thermo-time switch is at fault~ https://www.google.com/#q=1990+toyota+corona+thermo+time+swi tch&tbm=shop

The running problem sounds like the carb needs overhauled, most likely wasn't setup for this trash they try to tell us is fuel today. As for the battery light, double check and see if it has a voltage regulator on the drivers inner fender in the engine compartment, you right in the years when things were changing on the charging systems, anyway if it has one replace it. If it doesn't then the charge circuit will have to be checked. HTH

thanks for ya answer i will look for a second hand carby. some times it sounds like it has a gut full of fuel and struggles to turn over sort of sounds like the timing is out. wait 10 minutes and she starts straight up for a minute

I hope you have better luck finding a good one than I have had. Timing is critical on these first generation Toyota engine controls, so make sure it is right.

Might be a good idea, those carbs are tricky to overhaul, just make sure the shop has good reviews and has at least a couple of certified techs working there.

put a boot inside a pick-n-pull..cannot tell you the wrecks that I've wrecked needing to get to the parts...there is a cart with a cutting torch if you're stuck...but point is I learned all about stuff..from messing around trying to rescue an assembly from a similar make~ fun to bring a toolbag and a camera...so things you did not see the first walk around, you can spot from the pictures...cannot tell you the number of cars I bought from the junkyard....a Toyota corona was one of them~ put together from all junked corona~

hey so ive replaced carby and also fuel pump timing reset car still duying grrrrr

assure that the timing belt has not stretched so much that the timing is a little too retarded to keep running...you might turn the crank to TDC and note the position of the cams~ make sure the "wear shoe" isn't worn away...be sure the timing of the spark is correct...driven off the timing belt~ these wear every 80,000 miles~
