Default Engine starting probs. 1985

Hi: It started last year when sometimes it started up in a split second, other times it cranked for about 3 seconds before starting. This year it always takes the three seconds or so to catch. No other clues other than if I stop cranking at say the 2 1/2 second point and try again, I've got the split second start again, for that time only. Injectors? I've changed the plugs. Thanx

When are you experiencing the hard start, when the engine is cold or hot?

A hard start when the engine is warm is usually a sign of leaking injectors. It might be a full pressure issue. Have you put a gauge on it and checked how much pressure there is at start? If so, what's the pressure reading and does it hold steady or bleed down?

I haven't done that, cuz I wouldn't know how, nor do I have a guage. The reason i asked the question was because I was planning to take it to a garage and wanted to maybe estimate what the repair would be. Guessing about $600 - $800. Thanks for trying with the limited information I provided.
