My pickup 1992 toyota pickup 3vze 3.0 takes forever to start when its cold, I have to literally crank on it for like 1 hour to 2 hours then it'll start and after it starts it runs pretty good but it feels like it's losing power when I get on it. The guy that I bought it from didn't tell me how long ago the heads and valves were done but he says they had just been done. I checked the cold start injector and that works, I checked the fuel pressure it's got plenty, I've replaced the cap rotor and wires, I don't know how to check the fuel pressure regulator but that works ( it sucks fuel when I crank it over). What do I check, what do I do and what do I buy because I need to fix her asap!?!?

 

You have some contradictions here.
How did you check the fuel pressure and what was the reading?
Because "plenty" could be too much and a possible fuel regulator.

Do you have a FSM?
Did you check to see if there are any stored trouble codes?

 

Yes.^^^
O.P., if you need help online from people possibly thousands of miles away, you need to help us see what you are dealing with in as exact terms as possible.

To eliminate guesswork, fuel pressure gage piggy-backed on CSI: https://www.yotatech.com/forums/f199...l#post52312190

Also, the bestest CSI and CSI timer switch in the world that work perfectly on the bench will not work if they do not get ground on the engine. They get ground from the CSI timer switch mounting thread. All temp-senders and and the thread where CSI timer switch mounts should be cleaned to bare, shiny metal - at least every 25 years

Unfortunately I don't have a gage to test it, I did this by accident, but I cracked the bolt to the fuel rail and forgot to tighten it so when I cranked it over it sprayed a wall of fuel every where so I figure it had enough pressure.

what's a fsm?

I don't have a scan tool but the check engine light stays on when I get it started and drive it.

 

Fsm =field service manual. It's toyotas repair manual.

I'm not 100% sure on your model and engine but i think checking the engine light is the same as the others

On the side of the fuse box is a small plug with a flip cap, inside the cap it is labeled b+, fp, t, e1. Etc.

if you take a paper clip and jumper t and e1 and turn the key to on position the check engine light will blink your code. A quick Google search or youtube video will explain it fully. Post back with the code you get.

 

 

When I did this, all it did was fash the o/d off light so idk if that's a code or what and I don't have a fsm.

 

You need to count the flashes on the (check engine light) on the right.
If it flashes continuous then no code it stored.
Watch this short video pretty much explains it.

 

I got 1 4 2 4 , what is that?

look at this. I think you have 14 and 24 but you should be able to read that link and figure it out for clarification

 

I need the codes for a 3.0 bud not a 22re

 

They're the same. Toyota isn't going to make it THAT hard for you.

Dude, we can't do everything, It's a simple search, "google" do some leg work.
Your going to have to break the multi meter out and check out your VAFM and the air temp sensor.
You also are need to check the grounds and wiring for damage at the igniter to the ECM.
You really need to get a FSM, you might be able to down load one still.

 

I dont know the 3.0 but Toyota basically uses the same electrical set up as the 22. I have never had a Cold Start Injector to fail on me. Anytime I have had cold start issues, it is the Cold Start Injector Timing Switch that fails. You can test it using a Factory Service Manual or a Haynes Manual by putting the Timing Switch in a freezer and as it warms up seeing what the resistance readings are.

 

Thank you everybody I appreciate all the help, y'all are badass. I finally figured out that it the igniter computer next to the coil went bad and it isn't sending the right signals to fire to I have to find a new one.
