Taylor has not started either of Bolton's opening league fixtures but was one of nine changes made to the side for last night's Carling Cup second-round win at Southampton.
The 28-year-old has been linked with a move away from the Reebok Stadium, with West Ham said to be interested, but Coyle will not sell unless he is given a surprise budget to buy.
"Not unless the financial climate changes at our club," he said of a possible exit for Taylor.
"This has been a tricky pre-season because we have had no players out of contract, so we have had to be inventive in the Bosmans we have signed.
"I think we have done well with what we have, although I'd love to be one of these managers with £15 or £20million.
"But we've not got that so we don't moan about it, we get on with what we've got and make a real fist of it - but if things change I'd love to add one or two to help the group."
Ivan Klasnic marked his first start since rejoining Bolton with his first goal to see off Saints at St Mary's and the Croatian, plus the likes of Taylor, Sam Ricketts, Andy O'Brien and Ricardo Gardner, have been told by Coyle their chance will come.
However, they may have to bide their time following the Trotters' unbeaten start to the season with Coyle likely to revert to the team which beat West Ham last weekend for Sunday's clash with Birmingham.
He added: "We made nine changes from Saturday and that was for two reasons - to get a bit of freshness, and also to give these lads some game time under their belts because they will all be called upon in the Premier League.
"It's very early days. It's been a decent start but no more than that.
"We have to try to build on that and we have a tough, tough game on Sunday against Birmingham and we have to be ready for that because we will have to be at our best."
