Why would your 88 Toyota Camry not be getting fire It's turning over but not starting?

Answer 1

We have just replaced the engine, distributor, plugs and the ignitor, a few other nuts and bolts, it will turn over, and it's started for a second of two, but can't get it to stay running. Our mechanic wants an arm and a leg to even look at it, if anyone can help please let me know, or if you have any questions you can post them here and I'll answer, thank you so much.
