I have a 1994 Toyota 4Runner 5Speed and I'm having starting issues. I don't know if its a fuel pump problem or something else. When I try to cold start it, it will crank but not turn on. After 4-5 tries it fires up. It will almost die a couple times when warming up, like a stall, but will go back to normal. After that the truck run fine. Any ideas on what I should check first? Thanks.
