I had trouble starting the car, I put new spark plugs, new ignition coils, new lift bolts, and a new valve cover. Turns out the fuel pump was the issue so I replaced it with another fuel pump from another celica. The car started after that, but then out of nowhere it just did not want to start again. Friend of mine told me the battery was going bad, so I replaced the battery, and same problem.. the car cranks but doesn’t want to start. Last time I had it started it was idling pretty badly, and when I would change gears it would change, but the last time I drove it, it stalled. Since then it’s been sitting for two days now on the side of the road, and I have no clue why it doesn’t want to start back up. I’m gonna clean the EGR valve, MAF, Fuel Injectors, and IAC valve. If anybody has any advice, that would be greatly appreciated.

When you changed the Fuel Pump, there were wires on it to make it work. These wires are below the fluid level of the Fuel Tank and are subject to corrosion. (The car is 22 years old). The fuel Pump that you used to replace the older probably needed the same refurbishment. If you want to eliminate the Fuel Pump as a problem, sorry to say, you should remove the existing Fuel Pump and thoroughly remove the oxidation and rust from all the connections. Also, you are replacing an Old Fuel Pump with a used pump, which is also 22 years old. Your original problem is a typical one for cars with Fuel Pumps that are submerged inside the Fuel Tank.

I’ll try this out, and let you know how it turns out, thanks!

Fuel, air, spark

Fuel

• use fuel pressure guage, or, disconnecr one tv the flex lines fron firewall to block and see if fuel is pumped our
• check injectors are working with a noid light or mechanics stethoscope.
• check fuses

Air
- usually the least likely. Make sure air filter is clean and all wires are plugged in

Spark

• if plug wire is visible, check with a timing light
• if not (coil on top of plug), pull the coil/tube/plug and hold plug end near the block, you should see spark jump

Spark is good, Air is good, and as for fuel, I replaced the injectors with brand new ones. I also took apart the fuel pump, and found out that the wires weren't even connected... So the guy who had it last did a horrid job of putting it all back together. Battery needs to be charged, so I'm unable to see if it's working as it should. I checked fuses, and none were blown. A mobile mechanic suggested putting an entirely new housing, and fuel pump. I will keep you guys posted.

I replaced the fuel pump and I hear it whirring, but it still doesn’t want to start. I have no clue why it doesn’t want to start.

Did you:

• verify fuel is reaching the injector fuel rail
• check that injectors where operating?

Checked that fuel is reaching the rail, and it is. The injectors are operating as they should.

I decided to just sell it, and in the future hopefully I’ll find one in better condition. Thanks for all the tips lads.
